Answer:

This is a 10 percent increase

Step-by-step explanation:

Last week he spent 10 hours

This week 11 hours

percent increase = (new - original )/original * 100 percent

                             = (11-10)/10 * 100 percent

                             = 1/10 * 100 percent

                             = 10%

This is a 10 percent increase
