Question

Susan and her family took a trip during their vacation. They travelled a total of 3982 miles. They averaged 24 miles per gallon of gasoline. How much did the gasoline cost is the price per gallon was $2.48?

Answer 1

The gasoline cost $411.47.

Explanation:

This problem can be solved using rules of three.

The first step is finding how many gallons were used.

They travelled a total of 3982 miles. They averaged 24 miles per gallon of gasoline.

So

1 gallon = 24 miles

x gallons - 3982 miles

`24x = 3982`

`x = (3982)/(24)`

`x = 195.9`

195.9 gallons were used.

How much did the gasoline cost is the price per gallon was $2.48?

Each gallon costs $2.48. 195.9 gallons were used. So

$2.48*195.9 = $411.47

The gasoline cost $411.47.
