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?

Alina S.
Answer:

1.08(99.95x)+5 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 (99.95 x plus 0.08 * 99.95 x) + 5, which can be rewritten as 1.08 (99.95 x) + 5.
