The price of a diamond ring was reduced from $999.99 to $399.99. Find the percent in price.

We can start by finding the difference between the original price and the sale price:

$999.99 - $399.99 = $600

This means that the price was reduced by $600. To find the percentage decrease, we need to divide this amount by the original price and multiply by 100:

$600 ÷ $999.99 × 100 ≈ 60%

Therefore, the price was reduced by about 60%.

To find the percent decrease in price, we need to calculate the difference between the original price and the reduced price, and then express that difference as a percentage of the original price.

Step 1: Calculate the difference in price.
Original Price = $999.99
Reduced Price = $399.99

Difference = Original Price - Reduced Price
Difference = $999.99 - $399.99
Difference = $600.00

Step 2: Calculate the percent decrease.
Percent Decrease = (Difference / Original Price) x 100%

Percent Decrease = ($600.00 / $999.99) x 100%

Percent Decrease = 0.60 x 100%

Percent Decrease = 60%

Therefore, the percent decrease in price is 60%.
