Steven is moving to another city next weekend and wants to rent a moving truck. The rental rates for two companies in his area are shown below. Each company charges an initial fee for renting the truck, plus an additional amount per mile.

Company 1:
Miles: 30 Rental Charge: $53.55
Miles: 60 Rental Charge: $87.15
Miles: 90 Rental Charge: $120.75
Miles: 120 Rental Charge: $154.35
Miles: 150 Rental Charge: $187.35

Company 2:
Miles: 25 Rental Charge: $56.75
Miles: 50 Rental Charge: $78.00
Miles: 75 Rental Charge: $99.25
Miles: 100 Rental Charge: $120.50
Miles: 125 Rental Charge: $141.75

I'm supposed to figure out much they charge per mile, but my teacher said doing 53.55 / 30 is wrong so can some one help me.

Company 1:
Miles: 30 Rental Charge: $53.55

Let's do some estimating.

If the charge is $1 mile, then 30 miles would cost $30 for Company 1. 60 miles would cost $60. You know that a charge of 53.55 for 30 miles must be between $1 and $2 a mile.

The only way to find the correct charge is divide 53.55 by 30.

Perhaps you or the teacher misunderstood.
