Question

Suppose your gasoline tank holds 18 gallons of fuel. Your tank is currently 20% full. How many gallons of fuel do you need to add to fill the tank?

Answer 1

If u have a coulculater do 18 times .20 and that will give u the answer

Answer 2

I believe the answer is 14.4 gallons of fuel.
To get the answer, I did x over 18 = 20% of 100. You cross-multiply to get 100x = 360. Divide each side by 100 to get x = 3.6. Subtract that from 18 gallons to get your answer.
