Question

What is the percent change of 15$ to 21$

Answer 1

Answer:40

Step-by-step explanation:A change from 15 to 21 represents a positive change (increase) of 40%

Use the formula found below on this webpage to find the percent change by replacing the given values:

Percent change = [(21 - 15) / |15|] x 100 = [(6) / 15] x 100 = 40 % (increase)

Where: 15 is the old value and 21 is the new value. In this case we have a positive change (increase) of 40 percent because the new value is greater than the old value.

Answer 2
