Question

Manny took home a couple of his friends after soccer practice. He originally had 9 gallons of gas in his car. He used 1.02 gallons of gas to take one friend home and one half gallon to take the other friend home. How much gas did he have left in his car after taking both friends home?

Answer 1

gas left = 6.48 gallons

Explanation:

total gas = 9 gallons

gas used for one friend = 1.02 gallons

gas used for another friend = 1.5 gallons

total gas used = 1.02 + 1.5 = 2.52 gallons

gas left = 9 - 2.52 = 6.48 gallons
