Question

A car uses on average 27 miles per gallon if gas costs $4.04 per gallon, which of the following choices is closest to how much the gas would cost for the car to travel 2,727 typical miles?

Answer 1

`$408.04`

Explanation:

Given: `27 ("miles")/("gal"); " "($4.04)/("gal"); " " 2727` miles

Setup the dimensional analysis equation making sure all units cancel except for `$`:

`($4.04)/(cancel("gal")) xx (1 cancel("gal"))/(27 color(red)cancel" miles") xx 2727 color(red)cancel" miles" = $408.04`
