Question

Samantha found a great deal on sweatshirts at the mall and bought 5 sweatshirts at the

Super Duper sale price. Allison went the next day, but the sale was over, so she only bought
2 sweatshirts and paid $30 more per sweatshirt than Samantha. If the total cost of all 7
sweatshirts was $340, how much did one sweatshirt cost at the Super Duper sale price?

Answer 1

$40

Explanation:

You have two sweatshirts that cost $30 more the day after.

First, you do
`340 -(2*30)`

Second, you divide what you got above ($280), by 7 and voila, you have $40 per sweatshirt.
