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?

$40

Step-by-step explanation:

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

First, you do

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

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5

answer is  

d.

3.09
