The ratio of red jelly beans to yellow jelly beans in a dish is 3:4. if greg eats 3 red jelly beans and 6 yellow ones, the ratio is 4;5. how many jelly beans were originally in the dish?

  • Math -

    in original jar:
    number of reds = 3x
    number of yellows = 4x

    after the eating:
    number of reds = 3x-3
    number of yellows = 4x - 6

    (3x-3)/(4x-6) = 4/5
    16x - 24 = 15x - 15
    x = 9

    in original:
    reds = 3(9) = 27
    yellows = 4(9) = 36
    total in jar = 63

    check: 27 : 36 = 3 : 4
    after eating: 24 : 30 = 4 : 5
