Question

Nadia and Reggie want to rent bikes with two other friends. They have $150 to spend on bike rentals. The sign below show the bike rental rates.
Based on the information on the sign, the equation below can be used to determine the number of hours, h , the 4 friends can rent bikes with $150.
4 (9.75h - 3) = 150
Nadia says they have enough money to rent bikes for a maximum of 3 hours. Is Nadia correct? Show all of your work.

Answer 1

No! Nadia is not correct, the maximum is actually 4 hours. I know this because

4(9.75h+3)=150          distribute

39h-12=150              get the value h alone by adding 12

39h = 162                 divide both sides by 39

h=4.15

Answer 2

22 is the answer
