How much will it cost to drive 1500 miles at 4.00 dollars per gallon at 12 mpg?

First of all find out haw many gallons you will use.

every 12 miles you will use one gallon (12 mpg) and you are going 1500 miles so divide 12 into 1500

1500/12 = 125 This is the number of gallons you will use on the journey.

Next multiply the number of gallons you will use (125) by the price for a gallon (4.00 dollars)

125*4.00 = $ 500.00

So it will cost 500 dollars.
