Question

If 9 lbs.of pasta salad serves 15 people, how much pasta salad should you bring to a picnic with 76 people

Answer 1

15 people = 9 lbs pasta

1 people = 9/15 lbs. pasta

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

Answer 2

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
