Set it up as a proportion. If it costs $2.60 to go 29 miles, how much does it cost ($x) to go 340 miles?

29 miles 340 miles

------------ = -------------

$2.60 $x

Cross multiply (means and extremes):

29x = 340*($2.60)

x = 340*($2.60)/29

Solve for x, the cost of gas to go 340 miles.

Hi Brandon,

Can you calculate how many gallons it takes to drive that many miles?
