Knowing how to
Use percents can
help you!
Using Percents in the Real World
Percentages are commonly used in
everyday life. When you pay for
something, whether it is a product or a
service, percents are almost always
involved.
Most often percents are used to
calculate discounts, tips, and sales tax.
Common Uses of Percents
Discounts A discount is an amount that is
subtracted from the regular price of
an item.
discount = price • discount rate
total cost = price – discount
Tips
A tip is an amount added to a bill for
service.
tip = bill • tip rate
total cost = bill + tip
Sales tax Sales tax is an amount added to the
price of an item.
sales tax = price • sales tax rate
total cost = price + sales tax
Pay Less!
American Eagle is having a 10% off sale. If
Chandler wants to buy a sweater whose regular
price is $30.50, about how much will she pay
for the sweater after the discount?
Step 1: Find 10% of 30.50
30.50(.10) = 3.50
Discount = $3.05
Step 2: subtract discount from
original price.
30.50 – 3.05 = 27.45
Pay
More!
Elly is buying a dog bed for $40.00. The
sales tax rate is 7%. About how much will
the total cost of the dog bed be?
Step 1: Find 7% of 40.00
40(.07)=2.80
Step 2: Add to total bill to find
the amount he paid!
40 + 2.80 = $42.80
Pay
More!
Joseph’s dinner bill from Longhorns is $17.85. He wants to leave
a tip that is 15% of the bill. About how much should his tip be?
How much will he have to pay total?
Step 1: Find 15% of 17.85
17.85(.15) = 2.68
Step 2: Add to total bill to find
the amount he paid
2.68 + 17.85 = $20.83
