Question

what is the percent of increase from 5 to 7? write your answer using a percent sign (%).

Explanation:

Step1: Find the increase amount

The original value is 5 and the new value is 7. The increase amount is \( 7 - 5 = 2 \).

Step2: Calculate the percent increase

The formula for percent increase is \( \frac{\text{Increase}}{\text{Original Value}} \times 100\% \). Substituting the values, we get \( \frac{2}{5} \times 100\% = 0.4 \times 100\% = 40\% \).

Answer:

40%
