Question

If your car can drive 433 miles on a full tank of gas, find the miles per gallon if your gas tank holds 17.2 gallons? How much does it cost to fill your tank if gas is $2.85 per gallon?

Answer 1

-25.17 miles per gallon.

-It costs $49.02 to fill your tank.

Explanation:

-To find the miles per gallon, you can use a rule of three:

17.2 gallons → 433 miles

1 gallon → x

x=(1*433)/17.2= 25.17

If your gas tank holds 17.2 gallons, you car can drive 25.17 miles per gallon.

-To find the cost to fill your tank, you have to multiply the price per gallon for the amount of gallons that the tank can hold:

$2.85*17.2=$49.02

It costs $49.02 to fill your tank.
