Answer 1

The percentage increase in Angie's height is 3 %

Solution:

Given that, In one year, Angie's height went from 58 to 60 inches

To find: percentage increase

The percent increase between two values is the difference between a final value and an initial value, expressed as a percentage of the initial value.

The percent increase is given as:

`\text { percent increase }=\frac{\text { final value - initial value}}{\text { initial value }} * 100`

Here in this problem,

Initial value = 58 inches

Final value = 60 inches

Substituting the values we get,

`percent\ Increase = (60-58)/(58) * 100\\\\percent\ Increase = (2)/(58) * 100\\\\percent\ Increase = 0.0344 * 100\\\\percent\ Increase = 3.45 \approx 3`

Thus percentage increase in Angie's height is 3 %
