Question 2
What is the percent of change in this situation?(1 point)

% Round the answer to the nearest whole percent.

Answer 1

To find the percent of change, we can use the formula:

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

In this case:

- **Old Value** (cost to produce) = $558
- **New Value** (selling price) = $1499

Now let's calculate the difference and then the percent of change:

1. Calculate the difference:
\[
\text{New Value} - \text{Old Value} = 1499 - 558 = 941
\]

2. Calculate the percent of change:
\[
\text{Percent of Change} = \left( \frac{941}{558} \right) \times 100 \approx 168.4\%
\]

Rounding to the nearest whole percent gives us:

\[
\text{Percent of Change} \approx 168\%
\]

Therefore, the percent of change in this situation is **168%**.
