Excel Problem: (150 points)
As the new manager of Toys America, a retail toy store chain, one of your jobs is to keep
track of items sold and returned. You have designed several worksheets to help you keep track
of all items in stock and the revenue made from these items. Revenue is defined as retail price
times quantity. Expenses are the wholesale price of an item and the shipping costs. The
markup is your profit.
Items This worksheet contains information about the name of the item in stock, the
company that makes it, the category id of the item, the wholesale cost and the quantity sold in
the last month. Wholesale cost is the cost of the goods purchased straight from the
manufacturer. You will use this information later to write formulas and perform calculations.
Markup This worksheet contains information about the markup percentage for each
item you sell. This percentage is based on the wholesale cost of each item and there is a
different markup percentage for each category ID. The retail price of an item is the wholesale
price plus the markup and shipping. Retail =Wholesale + Markup + Shipping Cost
Units This table contains information about shipping costs associated with purchasing
the item from the manufacturer and also some conversions you may need. There is a $2.00
shipping charge for every 10 lbs of toys shipped. In order to calculate the retail cost of your
items in stock, you will also need to calculate the shipping cost and add it to the wholesale cost.
Misc This worksheet contains information about whether or not the item requires adult
assembly before it can be played with and if it is safe for children under age 3. A TRUE in the
corresponding cell indicates that this item does require assembly or that it is safe for children
under 3 years of age (respectively). You will also find the shipping weight in kilograms for each
item of a particular category. For instance, one Krazy Racer weighs 3.5 kg.
Please refer to the Excel worksheets shown at the end of this exam to answer the
following questions. Use cell references whenever possible.
1
1. Write a formula for cell Misc!D2 to calculate the total shipping cost for one CIS Barbie. Write
this formula so that it can be copied down the column. (Round to two decimal places.)
=KGS * #/KG /10 * $/10 KG = $ = ROUND(C2 * UNITS!B$5/UNITS!B$3 * UNITS!C$3,2)
2. Write a formula for Items!F3 to calculate the total shipping costs for all Krazy Racers. Write
this formula so that it can be copied down the column.
=VLOOKUP(A3,misc!A$2:D$7,4,FALSE)*items!E3
3. Write a formula for cell Items!G3 to be copied down to calculate the retail cost for one
Krazy Racer in stock.
=D3+(D3*HLOOKUP(C3,Markup!A$2:E$3,2,FALSE))+(F3/E3)
4. Write a formula for cell Items!H3 to calculate the total revenue for all of the Krazy Racers
sold this past month. Write this formula so that it can be copied down the column.
=E3*G3
5. Write a formula for cell Items!I3 to calculate the total profit for all Krazy Racers sold in the
past month. Write this formula so that it can be copied down the column.
=H3-(D3*E3)-F3
6. Write a formula for Items!G9 to calculate the total retail cost for items in stock. Write this
formula so that it can be copied across the row. Use a function.
=SUM(G3:G8)
7. Write a formula for cell Items!H11 to calculate the total revenue made for all items
manufactured by Fisher Price.
=SUMIF(B3:B8,"Fisher Price",H3:H8)
8. Write a formula for cell Items!H12 to answer TRUE/FALSE if there are more types of
products made by Matel than Hot Wheels.
=COUNTIF(B3:B8,"Fatel")>COUNTIF(B3:B8,"Hot Wheels")
9. Write a formula for Items!H13 to answer TRUE/FALSE if none of the items in stock requires
assembly.
=NOT(OR(misc!B2:B7))
2
10. Write a formula for cell Items!H14 to answer TRUE/FALSE if Krazy Racers is the only item
that requires assembly.
=AND(misc!B6,NOT(OR(misc!B2:B5,misc!B7)))
11. You are deciding whether or not to lower your prices for specific items in stock. Price
reduction is based on the following criteria:
 If the item is a low-selling item (meaning that less than 100 of that item have been sold),
you will reduce the retail price for each item by 15%.
 If this is not the case, but less than 250 of the item have been sold, you will reduce the retail
price for each item by 10%.
 If you have sold at least 250 of the item, you will not reduce the price.
Write a formula to be placed in cell Items!J3 to calculate the discounted price (if applicable) of
Krazy Racers. Write this formula so that it can be copied down the column.
=IF(E3<100, G3-G3*0.15, IF(E3<250, G3-G3*0.1,G3))
12. You have just started a new layaway plan at your store. You will allow customers to put
their items in layaway for 3 months and make weekly payments to completely pay for the
items. You will charge 10.5% annual interest compounded monthly. If a customer wants to
buy a Dream Castle, what would the weekly payment be for this item? Write an Excel
formula that would calculate this payment. Assume there are exactly four weeks in a month
and the customer will pay the reduced price for the item.
= PMT(.105/12, 3, items!J8)/4

Access (150 points)
To enhance your ability to keep track of items in stock, you have created an Access database to
accomplish this task. You will have a total of items in stock at the beginning of the month.
During the month sales will be made and items will be returned. One of your tasks will be to
keep track of your item inventory remaining at the end of the month. You have set up 4 tables.
They are as follows:
Items This table contains information about each item in stock. Each items has an ID#, name
category ID, supplier ID, wholesale cost (written as ws cost) and retail cost. The wholesale cost
is the cost the manufacturer charges you for the goods. The retail cost is the wholesale cost
plus any markup you have imposed on the item. Also included in this worksheet is the in stock
total for your items for the beginning of the month.
Suppliers: This table contains information about each supplier for all items in stock. Each
supplier has an ID#, name and contact person for whom you work with at that company.
Sales: This table contains information about all sales of the items you have in stock. Sales are
listed by item#. Also included, is the quantity of each item sold for a particular purchase and
the date of the sale.
Returns: This table contains information about the items that have been returned to your
store. Each return is listed by item#. The dates of the returns and reasons for the returns are
also listed. Assume that only one item has been returned for each record listed.

1. Create a relationship diagram for the Employee database
a. Identify the primary keys and foreign keys
b. Establish the relationships between each table
FK: Item# on Sales
FK: SupplierID on Items
FK: Item# on Returns
FK: ReasonCode
on Reason
2. Has referential data integrity been violated between any tables? If so, identify the orphans.
Yes. Item# 7 on in the Sales table is an orphan.

3.
Using the Access design view below, write a query to result in the following: The item# and name of
all items that were sold between December 1, 2012 and December 10, 2012. Sort lowest to highest
by item# and by date starting from the most current.
