Answer:
That would be a 30.9 or 31% increase!
Explanation:
Formula: % increase = Increase ÷ Original Number × 100
To find the increase subtract the new increase number by the original.
72-55 = 17
Increase: 17
Original: 55
Here's the equation when using the formula:
17/55*100
That would get you the answer of 30.909091
