x=-1/5p + 90

A) Find the number of TVs she will sell if the price is $375

B) WRite a formula for the revenue when x TVs are sold

C)Find the revenue generated by TV sales if they are priced at $400 each

Can you do any of this? Part A is a matter of substituting $375 for p and solving for x. Just where are you having trouble (and the why would help us help you).
