Question

The​ U.S.-based motorcycle manufacturer says that it expects to build 141 comma 000 motorcycles this​ year, up from 129 comma 000 last year. Find the percent of increase in production.

Answer 1

To find the percent increase in production, you can use the formula:

\[
\text{Percent Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100
\]

In this case:

- Old Value (last year's production) = 129,000
- New Value (this year's production) = 141,000

Now, plug in the values:

\[
\text{Percent Increase} = \left( \frac{141,000 - 129,000}{129,000} \right) \times 100
\]

\[
\text{Percent Increase} = \left( \frac{12,000}{129,000} \right) \times 100
\]

\[
\text{Percent Increase} \approx 0.09302326 \times 100
\]

\[
\text{Percent Increase} \approx 9.30\%
\]

Therefore, the percent of increase in production is approximately **9.30%**.
