The demand for concert tickets depends on the price per ticket. Thus, the demand is a function of the price. If this function is called D(p), use the formula below to compute D(15), the demand for tickets when the price is $15. D(p) = 2115 - 2p - p2

A.
D(15) = 1120

B.
D(15) = 2115 - 225

C.
D(15) = 2115 - 60

D.
D(15) = 2115 - 255
