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.

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%.
