If I have a 12 pound case of chicken, and each serving is 12 ounces how much does each serving cost? The case is $54.82

well, 1lb = 16oz.

in 12 lbs there are 12*16 oz, namely 192 oz.

since each serving is 12 oz, how many times does 12 go into 192? 12 : 192 = 16.

well, it turns out that the 12lbs case is $54.82, so the 54.82 yields 16 servings then.

how many times does 16 go into 54.82? 54.82 : 16 = 3.42625.

64 divided by 12 = 54
