Question

a boy is 27 inches tall. five months later, he is 30 inches tall. what is his percent of change?

Explanation:

Step1: Calculate height change

$30 - 27 = 3$ inches

Step2: Find percent change

$\text{Percent Change} = \frac{\text{Change in Value}}{\text{Original Value}} \times 100\% = \frac{3}{27} \times 100\%$

Step3: Simplify and compute

$\frac{1}{9} \times 100\% \approx 11.11\%$

Answer:

The percent of change is approximately $11.11\%$ (or exactly $\frac{100}{9}\%$)
