A buisness exstended their building from 15000 square feet to 20,550 what is the percent increase

Answer 1

exactly a 37% increase

the increase is 20550-15000= 5550

5550/15000 = 0.37 = 37%

a 100% increase would be to double to 30000

a 33 1/3% increase would be to add 1/3 or 15000+5000 = 20000

20550 is a little more than 20000, 37% is a little more than 33 1/3%
