an increase of 6 hours

an increase of 37.5%

an increase of 27.3%

a decrease of 6 hours

If you would like to know the change in Debra's hours, you can calculate this using the following steps:

x% of 16 hours is 22 hours

x% * 16 = 22

x/100 * 16 = 22

x = 22 * 100 / 16

x = 137.5%

137.5% - 100% = 37.5%

22 hours - 16 hours = 6 hours

The correct result would be: an increase of 6 hours, and an increase of 37.5%.
