A single rose street vendor has found that the number of roses he sells in a day depends on the price charged per rose. The more the vendor charges for a rose, the fewer people decide to purchase one. The function p(x)=2.00+0.50x represents price charged per rose where x is the number of $0.50 increases he changes over a price of $2.00 per rose. The function f(x)=80-2x represents the number of customers expected to purchase a rose where x is the number of $0.50 increases charged per rose over a price of $2.00 per rose. What does (p*r)(x) represent in the context of the situation? A. (p*r)(x) represents the revenue from selling r(x) roses at a cost of p(x) per rose
B. (p*r)(x) represents the profit from selling r(x) roses at a cost of p(x) per rose.
C. (p*r)(x) represents the profit from selling p(x)) roses at a cost of r(x) per rose
D. (p*r)(x) represents the revenue from selling p(x) roses at a cost of r(x) per rose
