Find the difference between the first number and the second number and divide by the first number then change to a percent. 50-40=10 10/40=.25 or 25 percent increase. Don't forget to divide by the beginning amount because 50 to 40 is different.
First, change the percent to a decimal which is done by dividing by 100. Then, multiply that result by 80:40 / 100 = 0.40.4 x 80= 32
