At Hughes Middle School, the 7 th grade class began the year with $ 100 and sold t-shirts for $ 10 profit per shirt. The 8 th grade class began the year with $ 200 and sold t-shirts for $ 6 profit per shirt. How many shirts does each class need to sell for both classes to have the same amount of money if they sell the same number of t-shirts?

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

step-by-step explanation:

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
