Question

Montel Edwards bought a 20-oz package of ham for $8.75. He can buy a 3-ib package of ham for $15.60. How much will he save per ounce by buying the 3-ib. package of
ham instead of the 20-oz. package (Note: 1 lb. = 16 ounces)?
9.6 cents ter ounce
10.5 cents per ounce
11.3 cents per ounce
12.8 cents per ounce
None of these choices are correct.

Answer 1

C. 11.3 cents per ounce

The 20-oz ham is $8.75/20 ounces = $0.4375/ounce

The 3-lb ham is 3 x 16 ounces = 48 ounces. Cost is $15.60/48 ounces = $0.325/ounce.

The difference in cost per ounce is 0.4375 - 0.325 = $0.1125 = 11.3 cents/ounce, rounded.
