A casting weighed 148 lb out of the mold. It weighed 141 lb after finishing. What percent of the weight was lost in the finishing?

Answer :

Final answer:

To find the percentage of weight lost in the finishing of a casting, we can use the formula: (weight loss / initial weight) x 100%.

Explanation:

To find the percent by which the weight was lost, we need to calculate the weight loss as a percentage of the initial weight. The initial weight of the casting was 148 lb and it weighed 141 lb after finishing. The weight loss is the difference between the initial weight and the final weight, which is 148 lb - 141 lb = 7 lb. To find the percent weight loss, we use the formula:

Percent weight loss = (weight loss / initial weight) x 100%

Substituting the values, we have:

Percent weight loss = (7 lb / 148 lb) x 100% = 4.73%

Therefore, the casting lost approximately 4.73% of its weight in the finishing process.
