Answer 1

To calculate the percentage increase in sales from 2010 to 2013, we use the formula for percentage increase:

\[
\text{Percentage Increase} = \left( \frac{\text{Final Value} - \text{Initial Value}}{\text{Initial Value}} \right) \times 100
\]

In this case:
- Initial Value (2010 Sales) = $98,000
- Final Value (2013 Sales) = $110,000

Now, plug these values into the formula:

1. Calculate the difference:
\[
\text{Final Value} - \text{Initial Value} = 110,000 - 98,000 = 12,000
\]

2. Calculate the percentage increase:
\[
\text{Percentage Increase} = \left( \frac{12,000}{98,000} \right) \times 100 \approx 12.24\%
\]

Based on the answer choices provided, the closest option to 12.24% is:

**E: 12.2%**
