"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 $\frac{\text{Old Price}}{-} 0.15$
"Old Price" = ($75)/0.15 "Old Price" =$500
"New Price" = \$425#
