The gasoline cost $411.47.

Step-by-step 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

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.
