Let M = Marked Price or Selling Price
Cost = $85
25% Profit = (1.25) (Cost) = (1.25) (85)
15% Discount = .85M
.85M = (1.25) (85)
.85M = 106.25
M = $125.00
CHECKING:
Cost = $85
25% Profit = 125% of $85 = 1.25 x $85 = $106.25
85% of the Marked Price must equal $106.25.
Or, 15% discount of $125 = 85% of $125 = (.85) ($125) = $106.25
Hope this helps you Tori.
