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%.
