Problema Solution
John learned that after overhauling the carburetor in his car he would use only 80% as much gas. Last month, before overhauling his carburetor, he used 125 gallons of gas. Assuming that John drives the same of miles next month, how many gallons of gas can he expect to save next month after overhauling his carburetor?
Answer provided by our tutors
the 125 gallons used minus 80% of 125 = the difference in gas
125 - 0.80*125 = 25 gallons
he can expect to save 25 gallons of gas.
