A furnace used 40% of the fuel in its tank in the month of March and then used 25% of the remaining fuel in the month of April. At the beginning of March, there were 240 gallons of fuel in the tank. How much fuel (in gallons) was left at the end of April?

Respuesta :

March: 240 * 0.4 = 96 used
240 - 96 = 144 remains in the tank

April : 144 * 0.25 = 36 used
144 - 36 = 108 remains in tank

answer: 108 gallons left at the end of April
