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/39=138/39
3.6 when rounded
