A diamond ring was reduced from $999.99 to $689.99. Find the percent reduction in the price. Round the answer to the nearest tenth of a percent, if necessary.

The formula to calculate the percent reduction is: \[\text{Percent reduction} = \frac{\text{Original price} - \text{Reduced price}}{\text{Original price}} \times 100\%\] Given: Original price = $999.99 Reduced price = $689.99 Let's calculate the percent reduction: \[\text{Percent reduction} = \frac{999.99 - 689.99}{999.99} \times 100\%\] \[\text{Percent reduction} = \frac{310}{999.99} \times 100\%\] \[\text{Percent reduction} \approx 0.31003 \times 100\%\] \[\text{Percent reduction} \approx 31.003\%\] Rounded to the nearest tenth of a percent, the percent reduction in the price is approximately 31.0%.
