part a: the first cereal is y=7x and the second one is y=10x so they are $3 apart.

part b: y=7*4 and y=10*4 is $12  apart so she will save $12 each month.

Hi, Taylorboy120!

So, the new brand costs 7 dollars a box. 
x is the number of boxes. If you let x = 1 box, y = 7 * 1 = 7 dollars per box.
So the savings brand is 7 dollars a box, and the original is 10 dollars per box.
If he buys 5 boxes in each month, he saves 5 times (10-7) dollars each month or 15 dollars per month.

I hope this helps!!
