Explain how you solved this problem and what you got as your answer.
Please don't only give me the answer, actually EXPLAIN.

Answer 1

$3.60 per pound

Explanation:

you can set up a proportion: $ / lbs = $ / lb

let 'x' = cost of 1 pound of chicken:

9 / 2.5 = x / 1

cross-multiply:

2.5x = 9

x = 9/2.5

x = 3.6
