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.

Answer 1

$16

Explanation:

a) Original Money = $12

Saving money = y = 8(1) = $8

Difference = 12 - 8 = 4

In short, Your Answer would be $4

b) It would be 4 times than the single time saving which is 4,

so = 4 * 4 = 16

In short, Your Answer would be $16

Hope this helps!

Answer 2

A) To buy one box of the new cereal it will be y=8*1 so 8$. 12-8= 4. So the original brand is 4$ more.

B) 4*4=16$
