Performance Task: ASB Student Treasurer Grade 7NS1-3 You have just been elected as the student council treasurer. Your job is to maintain a budget that includes all of ASB’s expenses and fundraisers. ASB will be having a back to school dance next week. You will have to keep track of all expenses related to the dance and help determine how much each ticket will cost in order to maintain a positive balance. The ASB budget started with an opening balance of $142.68. Session 1: Planning for the Dance 1. ASB must hire a DJ for the dance and decorate the school cafeteria. The DJ charges $75 per hour and in the past ASB has spent about $80 on decorations. If the dance is held from 1:30 to 3:00pm, does ASB have enough money to pay for the DJ and $80 of decorations? What would be the balance of the ASB budget after paying for the DJ and decorations? 2. Previous dances have sold an average of 100 tickets. Assuming you sell the same number of tickets, what’s the lowest ticket price ASB could charge in order to cover the dance expenses? Show your work and explain how you found your answer. 3. ASB is in charge of planning many student activities throughout the year so it would be a good idea to maintain a positive balance in the budget for future expenses. How much should ASB charge for each dance ticket if they wanted to end with a positive balance of at least $200? Show your work to support your answer. 4. You need to have enough money in order to pay for the DJ and buy the decorations before the dance starts, so ASB decides to sell pre-sale tickets. How much should ASB sell the pre-sale tickets for, in order to have enough money to pay for expenses before the dance, assuming of the 100 tickets are sold pre-sale? 5. If you sell the remaining tickets at the door, how much should you charge at the door in order to maintain the minimum $200 balance in the ASB budget? Session 2: Ticket Pre-Sale 6. ASB ended up selling 42 tickets at the pre-sale price. Fill in the table below to show ASB’s budget balance after they paid for the DJ and finished their ticket pre-sale. 7. The ASB president doesn’t think there’s enough money in the budget to purchase $80 worth of decorations. Do you agree or disagree? Explain. Session 3: After the Dance 8. If the decorations cost $78.96 and 67 tickets were sold at the door, what would be the ending balance in the ASB budget? Show your work and complete the table above accordingly. ASB Budget: Description Opening Balance DJ Fee Pre-Sale Tickets Debit Credit Balance +$142.68 $142.68 Scoring Rubric: Responses to this item will receive 0-2 points, based on the following: Session 1: Planning for the Dance Part 1 2 points: The student demonstrates a thorough understanding of how to apply mathematics to solve problems involving operations with rational numbers and computation with multi-digit decimals. The student correctly computes the cost for the school dance including the cost for the DJ and the decorations from the starting balance. Student is able to calculate with accuracy the balance of the ASB budget after deducting all expenses. 1 point: The student demonstrates a partial understanding of how to apply mathematics to solve problems involving operations with rational numbers and decimal reasoning. The student provides an inaccurate budget balance, but correctly computes either the cost of the DJ or is able to determine whether there is enough money to pay for $80 worth of decorations. 0 points: The student shows inconsistent or no understanding of how to apply mathematics to solve problems involving operations with rational numbers and computation with multi-digit decimals. Student is unable to compute the cost of the DJ or is able to state whether there is enough money to pay for $80 worth of decorations. Student is unable to correctly calculate the balance of the ASB budget. Part 2 2 points: The student is able to use mathematical reasoning to correctly compute the minimum cost for the school dance ticket in order to cover the dance expenses. The student is able to clearly show all work and provides an appropriate explanation to justify the solution. 1 point: The student is able to compute the minimum cost of the ticket to cover all expenses but is unable to clearly provide an appropriate explanation to justify the solution. 0 points: The student is unable to accurately calculate the lowest ticket price to charge in order to cover dance expenses. Part 3 1 point: The student is able to calculate with accuracy the cost ASB should charge for each dance ticket to maintain a positive balance of at least $200. Student is able to clearly show all work and provides an appropriate explanation to justify the solution. 0 points: The student demonstrates a limited understanding of the task and is unable to calculate what the ticket price should be to end with a positive balance of $200. Part 4 2 points: The student demonstrates a thorough understanding of how to apply mathematics to solve problems involving operations with rational numbers. The student correctly computes the cost of pre-sale tickets assuming 2/5 of the 100 tickets are sold prior to the dance. 1 point: The student demonstrates a partial understanding of how to apply mathematics to solve problems involving operations with rational numbers and decimal reasoning. The student is able to compute the cost of a pre-sale ticket, but incorrectly determines the cost of the pre-sale ticket if 2/5 of the 100 tickets are sold. 0 points: The student shows inconsistent or no understanding of how to apply mathematics to solve problems involving operations with rational numbers and computation with multi-digit decimals. Student is unable to compute the cost of the pre-sale ticket or the cost of the pre-sale ticket if 2/5 of the 100 are sold. Part 5 1 point: A thorough understanding of operations with rational numbers. Student is able to correctly determine the cost of selling tickets the door for the remaining tickets in part 4, to maintain a minimum$200 balance in the ASB budget. 0 point: The student is unable to calculate the cost of selling tickets at the door in part 4, to maintain ASB Budget. Session 2: Ticket Pre-Sale Part 6 2 points: The student demonstrates a thorough understanding of how to apply mathematics to solve problems involving operations with rational numbers and computation with multi-digit decimals. The student correctly computes the cost for of selling 42 tickets at the pre-sale price. Student is also able to fill-in the table accordingly, to show the ASB budget balance after paying for the DJ and after selling tickets pre-sale. 1 point: The student demonstrates a partial understanding of how to apply mathematics to solve problems involving operations with rational numbers and decimal reasoning. The student accurately fillsin the table to show the ASB budget balance but makes a computational error in calculating the ending balance. 0 points: The student shows no understanding of how to fill-in the table and makes computational errors to calculate the ASB budget's ending balance. Session 3: After the Dance Part 7 1 point: The student is able to use mathematical reasoning to correctly compute the amount to determine if there is enough money in the budget to purchase $80 worth of decorations. The student is able to clearly show all work and provides an appropriate explanation to justify the solution. 0 points: The student is unable to use mathematical reasoning to correctly compute the amount to determine if there is enough money in the budget to purchase $80 worth of decorations.
