Hi philipssonicare

As I wrote in my post, Revenue of Erases = e * x

We know p = 0.20 + e

now from statement 1) we know x = y + 10

From statement 2) we know 30 = p * y

For the second statement it can be rearranged to 30 = (0.20 + e) * y

Now even if I combine both I get 30 = (0.20 + e) (x -10)

I have one equation and two variables.

I hope this helps.
