46%
A change from 50 to 73 represents a positive change (increase) of 46%
Use the formula found below to find the percent change by replacing the given values:
Percent change = 73 - 50|50| x 100 = 2350 x 100 = 46 % (increase)
Where: 50 is the old value and 73 is the new value. In this case we have a positive change (increase) of 46 percent because the new value is greater than the old value.
hope this help! ^^
