If your traveling 3400 miles and gas is 4.00 per gallon and the car gets 30 miles per gallon how much would that cost?

Answer 1

Divide the miles per gallon into the number of miles traveled to give you the number of gallons used.

Then multiply the number of gallons used by the cost of the gas per gallon to give you the total cost.

As this is your homework you need to do the actual sums yourself to get the answer or you will not learn how to do this sort of calculation.
