Mark bought four times as many apples as Harry and three times as many apples as Martin. If Mark, Harry, and Martin purchased less than a total of 190 apples, what's the greatest number of apples that mark could have purchased?

  • Math -

    x = Mark's
    y = Harry's
    z = Martin's

    x = 4y so y =1/4 x
    x = 3z so z = 1/3 x

    x + 1/4 x + 1/3 x < 190
    12/12 x + 3/12 x + 4/12 x <190

    Solve for x.
