Question

How do I put this in a equation?

Answer 1

They started with 115 apples, and ate 8 apples each day.

Thus our expression for that would be

`115-8x`

Now, we want to find after how many days they had 19 apples left. Thus, let's set the expression equal to 19 and solve for x.


`115 - 8x = 19`

`96 = 8x`

`\boxed{x = (96)/(8) = 12}`
