In a certain state, gasoline stations compute the price per gallon p, in dollars, charged at the pump by adding a 4 percent sales tax to the dealer's price per gallon d, in dollars, and then adding a gasoline tax of $0.18 per gallon.Which of the following gives the dealer's price per gallon d in terms of the price per gallon p charged at the pump?

(A) d = p - 0.22

(B) d = P/ 1.22

(C) d = (P/1.04) – 0.18

(D) d = (P - 0.18)/1.04

(E) d = (P-0.04)/1.18


好像没有筒子问过~这道题好困扰我，望NN相助
