Question 133970
Demand for pools. Tropical pools sells an aboveground model for p dollars each. The monthly revenue from the sale of this model is given by 
R= -0.08p^2 + 300p. Revenue is the product of the price and the demand (quantity sold).

Factor out the price on the right-hand side of the formula.

On the right side we have this:

-0.08p^2 + 300p

Factor out 0.08p and divide into -0.08p^2 and 300p separately.

0.08p(-p + 3750)

Done!
