Question:

Aaron is staying at a hotel that charges $99.95 per night plus tax for a room. A tax of 8% is applied to the room rate, and an additional onetime untaxed fee of $5.00 is charged by the hotel. Which of the following represents Aaron’s total charge, in dollars, for staying x nights?

Andrea F.
Answer:

A: (99.5 + 0.08x) + 5 B: 1.08(99.95x) +5 C: 1.08(99.95x +5) D: 1.08(99.95 +5)x The correct answer is B. The total charge that Aaron will pay is the room rate, the 8% tax on the room rate, and a fixed fee. If Aaron stayed x nights, then the total charge is left parenthesis 99.95 x plus 0.08 cross times 99.95 x right parenthesis plus 5, which can be rewritten as 1.08 open parentheses 99.95 x close parentheses plus 5. When solving SAT math questions keep in mind solving for C first. Usually SAT math questions increase numerically from A to D so if you solve for C and know that the answer should be higher or lower you can automatically eliminate some choices.
