Answer 1

To determine the percent of change, you can use the formula for percent change:

\[
\text{Percent Change} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100
\]

In this case:
- The Old Value (cost) = $558
- The New Value (selling price) = $1499

Now, plug the values into the formula:

\[
\text{Percent Change} = \frac{1499 - 558}{558} \times 100
\]

Calculating the numerator:

\[
1499 - 558 = 941
\]

Now, calculate the fraction:

\[
\frac{941}{558} \approx 1.684
\]

Finally, multiply by 100 to get the percent change:

\[
1.684 \times 100 \approx 168.4\%
\]

Rounding to the nearest whole percent, the percent of change is:

**168%**.
