A pet hotel charges $60 per night to keep a goat. When the goat arrives, there is a mandatory $20 examination fee.

Question

Part A: Write a function rule for the total cost T, including the mandatory examination, for a goat to stay at the hotel for n days.

Part B: How much would an 8-night stay cost?

Part C: Does a 4-night stay cost half as much as an 8-day stay since it is half the time?

Answer 1

A: Part A: T = 60n + 20

Part B: 8-night stay cost = 60(8) + 20 = 500

Part C: No, a 4-night stay cost = 60(4) + 20 = 300, which is not half of 500.
