Question

Julina is planninf a 1224-mile driving trip. Her car gets an average of 34 mpg, and the cost of gas is about $3.56/gallon. What is the approximate driving cost of the trip

Answer 1

Julina's car can travel 34 miles with one gallon of gas, so she will need

$\dfrac{1224}{34}=36$

gallons of gas to make the whole trip.

Since one gallon costs $3.56, 36 gallons cost

$36\times 3.56=128.16$

dollars.
