Question

A steel bar that originally weighed 15.62 pounds is turned down on a lathe until it weighs 14.48 pounds. What percent of the original bar is waste? (Round your answer to the nearest tenth.)

Answer 1

1. The information, given in the problem, that you need to solve it, is:

- A steel bar that originally weighed 15.62 pounds.
- Then it weighs 14.48 pounds.

2. Therefore:

15.62 pounds-----100%
14.48 pounds-----x

x=(14.48)(100)/15.62
x=92.70%

3. Now, you must substract both percents:

=100%-92.70%
=10.38%

The answer is: 7.3%
