A dealer has 10,000 gallons of unleaded gasoline. He wants to add just enough ethanol to make the fuel a 10% ethanol mixture. How many gallons of ethanol should be added?

  • math -

    (0)(10000) + x = .10(10000+x)
    times 10
    10x = 10000+9
    9x = 10000
    x = appr. 1111.1 gallons of ethanol
