Question

Sue buys a certain brand of cereal that costs $12 per box. Sue changes to a super-saving brand of the same size. The equation shows the price, y, as a function of the number of boxes, x, for the new brand.

y = 8x

Part A: How many more dollars is the price of a box of Sue's original brand of cereal than the price of a box of the super-saving brand? Show your work.

Part B: How much money does Sue save each month with the change in cereal brand if she buys 4 cereal boxes each month? Show your work.

I understand Part A, I just need Part B. Thanks! Fan and Medal!!!

Answer 1

So since you got the answer to A, that shows how much 1 box is

Answer 2

Yes..

Answer 3

I did 12-8=4... Do I Do 8-4=4?

Answer 4

But instead of saving 1, she wants to save 4

So you would multiply the amount she saved with one box by 4

Answer 5

so 4 x 4?

Answer 6

So the answer is 16?

Answer 7

If the savings of each box was $4, yes. It would be $16 a month

Answer 8

okay thanks sooooooo much!
