    9/15 = x/76 ... 9 lbs to 15 ppl = x lbs to 76 ppl

    cross multiply because this is a proportion

    (15) (x) = (9) (76)

    15x = 684

    x = 684/15

    x = 45.6 ... u should bring 45.6 lbs of pasta salad for 76 people

    15 people = 9 lbs pasta

    1 people = 9/15 lbs. pasta

    So, for 76 people = 9/15 * 76 = 45.6 lbs pasta
