$"New Price" = $425$

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" = $425$
