Question

How many boxes of frozen chopped spinach are needed to serve a party of 185 people, if each person is to receive a 3oz portion and each box weighs 4lb 6oz

Answer 1

185*3 = 555 / 34.6875 4*16 = 64+6 = 70 555/70 = ~7.9

You will need 8 boxes of frozen chopped spinach because you cannot have .9 of a box so you just round to 8.
