Final answer:
After making 405 (5oz) servings of mashed potatoes from a 145 lbs purchase, the waste percentage came out to be about 12.71%. This calculation is based on the assumption that all waste comes from unused potatoes.
Explanation:
First, let's determine the total weight of the potatoes used in the servings. Since each serving is 5oz, and there are 405 servings, we multiply these two values.
405 servings * 5oz/serving = 2025oz
There are around 16 ounces in a pound, so let's convert this to pounds for easy comparison.
2025oz ÷ 16 = 126.5625 lbs
You purchased 145 lbs, but only used approximately 126.5625 lbs for the servings, thus yielding a waste of:
145 lbs - 126.5625 lbs = 18.4375 lbs
The waste percentage is then the ratio of the waste to the total purchase, multiplied by 100%.
Waste Percentage = (18.4375 lbs / 145 lbs) * 100% = 12.71%
So, after making 405 (5oz) servings of mashed potatoes, the waste percentage came out to be about 12.71%, assuming all waste was from unused potatoes.
