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

The OA is D.

I'm really confused with this PS question. Please, can any expert assist me with it? Thanks in advanced.

Hello LUANDATO.

Let's take a look at your question.

It tells us that the price "p" is computed adding the 4% of the price per gallon "d" and then adding 0.18$. That is to say, $$p=d+d\cdot4\%\ +0.18\ \leftrightarrow\ \ \ p-0.18=d\left(1+0.04\right)\ \leftrightarrow\ \ d=\frac{p-0.18}{1.04}.$$ Therefore, the correct answer is D. I hope this explanation can help you. Feel free to ask me again if you have a doubt. Regards. _________________ GMAT Prep From The Economist We offer 70+ point score improvement money back guarantee.
