Let $n$ be the number of units.

You want to find Income - Expenditure = -1200

Can you set up an equation for this in terms of n?

3. The equation that i used was c(x)=7.00x+2150 and R(x)=8.70x
giving an equation of p(x)=1.70x-2150

then i plugged 1200=1.70x-2150 and i got 1970.588235 which is not the correct answer

Wouldn't $R(x) = 8.70x$? Since the way you've written it R(x) is constant and does not depend on x! Although I suspect that's a typo since it's correct later on
