Problema Solution

At current prices, Roberta can drive her car 8.2 miles per dollar of gasoline that she buys. Roberta and two of her friends decide to go on a road trip to a neighboring university that is 116 miles away and agree to split the cost evenly. To the nearest cent, how much money will each friend have to contribute to get to the university and back?

Answer provided by our tutors

The total distance to travel back and forth is:

116 + 116 = 232 miles

Since they pay $1 per 8.2 miles they will pay total of 232/8.2 dollars.

The total number of people traveling with the car is: Roberta and 2 friends that is 3 people.

We split 232/8.2 on 3 equal parts:

(232/8.2)/3 = $9.43

Each friend will have to contribute $9.43 for the ride to and from the University.
