Question

A sailboat rental company charges a fee of $78.75 plus $80.25 per hour to rent a sailboat. A second rental company charges customers a fee of $40 plus $95.75 per hour to rent a sailboat. How many hours would a customer have to rent a sailboat in order for both companies to charge the same total amount?

Answer 1

3.69 hours

Explanation:

y = 80.25x + 78.75

y = 95.75 + 40

85.25x + 78.75 = 95.75 + 40

-85.25x -40 -85.25x -40

38.75/10.5 = 10.5x/10.5

3.690476190..... = x

rounding

3.69 = x
