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.

its 50 miles away from the starting point
