Sam is going to cook a turkeys for 14 people and he wants to allow 3/4lb of Turkey for each person. 1lb=450g. Small 2kg-3.9kg.medium 4kg-5.4 kg.larg 5.5kg-7.2kg.extra large 7.3kg-9.2kg.but small/medium £5.99perkg. Large/extra large £4.99perkg.now how much will the Turkey for 14 people cost?

Answer 1

depends on which size turkey she gets, no?

Probably she wants to minimize the cost, so she ought to use as many large turkeys as possible, without buying a whole extra large turkey unnecessarily.

So, how many servings can she get from the largest of each size turkey?

each lb of turkey makes 4/3 servings.

small: 3900/450 * 4/3 = 11.55
medium: 5400/450 * 4/3 = 16.00

so, she can serve all 14 people with a single medium turkey.

This problem would have been more interesting had there been, say, 200 people, making it necessary to purchase turkeys of each size.
