Devon owns a house cleaning company and has to give price quotes to potential customers. He figures out his price by assuming a $25 base charge and then adding $8 for each bathroom and $4 for each other room. If he uses P to represent the price and B for bathroom and R for other rooms, which of these represents his price quote formula?

A P = 25 + 12(BR)

B P = 4R + 8B + 25

C P = 25(4R + 8B)

D P = (4)(8)(R + B) + 25
