This morning, Lisa's car had 28.07 gallons of fuel. Now, 2.9 gallons are left. How much fuel did Lisa use?

Answer 1

Greetings! Lets solve this shall we?

So, we must find out how many gallons of fuel she used! So, we take the total number of gallons used

Total Gallons = Number of Gallons used + Number of Gallons she has left

28.07 gallons = x gallons + 2.9 gallons........Then we subtract the 2.9 gallons from the 28.07 such that

x = 25.17 gallons used!

I hope this helped!
