Molly's hair was 20 inches long. Three years later it was 53 inches long. What was the percent increase, to the nearest hundredt
h, of Molly's hair length.
1 answer:
Find how much it grew:
53 - 20 = 33 inches.
Divide the amount it grew by the original length
33/20 = 1.65
Subtract 1:
1.65 - 1 = 0.65
Multiply by 100 for percent:
0.65 x 100 = 65%
The percent increase is 65%
