Question

a hotel cost $89 per night. sally will receive a $5 per night discount for paying in advance.a rental car cost $35 per day plus tax that totals $4 per day. which expression can sally use to find how much she will pay for the hotel and rental car for five days.

Answer 1

If she pays in advance: C = 5 ((89n - 5n) + (35n + 4n))
If she doesn't pay in advance: C = 5 (89n + (35n + 4n))

(Where n = day or night and C = cost [for rental car and hotel])
