Question

The cost of a pound of nails increased from $2.18 to $2.37. What is the percent of increase to the nearest whole-number percent?

Answer 1

9%

Step-by-step explanation:

To calculate the percentage of the increase, use the formula below:

`\%\text{ of change}=\frac{\text{Final Value-Initial Value}}{\text{Initial Value}}*100`

Substitute the given values:

`\begin{gathered} \text{Percent of change=}(2.37-2.18)/(2.18)*100 \\ =(0.19)/(2.18)*100 \\ =8.72 \\ \approx9\% \end{gathered}`

The percent of the increase is 9% (to the nearest whole number percent).
