You must add 3 to each number and then calculate the percent increase. Let's start with the former:

60 + 3 = 63
62 + 3 = 65
64 + 3 = 67
66 + 3 = 69

To calculate the percent increase, there are a few steps to follow; they are as follows:

1. Subtract new, larger number from original, smaller number
2. Divide this new number by the original number and multiply by 100.

63 - 60 = 3  =>  3 / 60 * 100  =>  0.05 * 100  =>  5. Ann will have a 5% change.
65 - 62 = 3  =>  3 / 62 * 100  =>  0.048 * 100  =>  4.84. Betty will have a 4.84% change.
67 - 64 = 3  =>  3 / 64 * 100  =>  0.047 * 100  =>  4.67. Carol will have a 4.67% change.
69 - 66 = 3  =>  3 / 66 * 100  =>  0.045 * 100  =>  4.55. Diana will have a 4.55% change.

Who will have the greatest percent of change in height?
Ann.

The correct answer is $90
