Question

Joshua is planning a 1020-mile driving trip. His car gets an average of 30 mpg, and the cost of gas is about $4.06/gallon. What is the approximate driving cost of the trip

Answer 1

30 miles for a single gallon.
first we find out how many gallons would be used.
number of gallons = 1020/30
gallons = 34.
and since 1 gallon costs $4.06
34 gallons would cost = 34 x 4.06 = $138.04

Answer 2

$138.04

Explanation:

The trip is 1020 mile and Joshua gets 30 miles per gallon. So the number of gallons needed can be found by dividing 1020 by 30.

Number of gallons needed =
`(1020)/(30)=34` gallons

If it costs $4.06 per gallon, 34 gallons would cost:

`4.06*34=138.04` dollars
