Answer:

90 % increase

Step-by-step explanation:

To find the percent increase, take the new number minus the original number

19-10 = 9

Divide by the original number

9/10 = .9

Change to a percent

.9 * 100 % = 90 % increase

Answer:

(final - initial / initial ) * 100

19 - 10/10 * 100

9/10 * 100

90 percent
