When Nancy started middle school she was 60 inches tall. When she started high school she was 66 inches tall. What was the percent change in her height?

To calculate the percent change in Nancy's height, first find the difference in her height: 66 inches - 60 inches = 6 inches. Then, divide the difference by her original height: 6 inches / 60 inches = 0.1. Finally, convert this decimal to a percentage by multiplying by 100, resulting in a 10% increase in her height.
