Question

Macy's is having a special on t-shirts. You can buy each at its regular price of $10.99, $11.90 and $10.08 or you can buy 3 t-shirts for $25. Julie bought one of each t-shirt at the sale price of $25. What percentage of the original total price did Julie save?

Answer 1

24.2%

Explanation:

The total regular price was:

$10.99 + $11.90 + $10.08 = $32.97

She paid:

$25

She saved: $32.97 - $25 = $7.97

Now we need to calculate what percent of $32.97 is $7.97.

To find what percent a number is of another number, divide the first number by the second number and multiply by 100.

percent saved = $7.97/$32.97 * 100 = 24.2%

Part (b)

Harry, Julie's best friend, also paid $25 for 3 t-shirts at a sale at another store. The sale price saved Harry 30% of the original price of the 3 t-shirts. What is the original price of Harry's 3 t-shirts? Who got the better deal?

Harry paid $25 and saved 30% over his original price. Let his original price be x. The original price was 100% of the original price since 100% means the whole amount. Since he saved 30%, that means he paid 70% of the original price.

70% of the original price = $25

70% of x = 25

70%x = 25

0.70x = 25

0.70x/0.70 = 25/0.70

x = 35.71

The t-shirts Harry bought had an original price of $35.71.

Harry got the better deal because he bought t-shirts with an original higher price for the same $25.
