noel and renaldo want to rent bikes with two other friends. they have $150 to spend on bike rentals.

bike rentals

rent 1 bike for 9.75 per hour.

special group rate

for group of 4 or more, save $3.00 per person.

4(9.75h-3)=150

noel says they have enough money to rent the bikes for a miximum of 3 hours. slove the equations for the number of hours,h, in order to determine whether noel is correct.

4(9.75h-3)=150

39h-12=150

39h=138

39h/39=138/39

3.6 when rounded

39h-12=150

39h=162

h=162/ 39=4.15, which means they can

Afford to rent for 4 hours.

This is for part (A)
