"New Price" = $425

Explanation:

Using the formula for Delta%:

Delta% = ("New Price " - " Old Price")/("Old Price")xx100

Substitute -$75 for the difference in the price and the change is -15%:

-15% = (-$75)/("Old Price")xx100

Divide both sides by 100:

-0.15 = (-$75)/("Old Price")

Multiply both sides by the ("Old Price")/-0.15

"Old Price" = ($75)/0.15

"Old Price" = $500

"New Price" = $425
