Charles decided that his old car could not make a 1200 mile trip; it might break down. Rather than take a chance on a big repair bill, and breaking down on the road, he decided to rent a car. The rental is $99 for a special three day weekend rate, with unlimited miles. If the rental car gets 30 miles per gallon and Charles has to pay $3.85 per gallon for gas, what is the total cost of gasoline and rental for the trip

Respuesta :

Using proportions, it is found that the total cost of gasoline and rental for the trip is of $253.

What is a proportion?

A proportion is a fraction of a total amount.

In this problem, the total cost is composed by:

  • The rental fee of $99.
  • The gasoline cost, of $3.85 per gallon, considering that 1200/30 = 40 gallons were used.

Hence, the total cost is given by:

C = $3.85 x 40 + $99 = $253.
