#"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#
