Answer :
Selling Price = $820
Mark up = 25% Cost Price
Selling Price = Cost Price + 25% Cost Price.
Let the cost price = x
Selling Price = x + 25% of x
820 = x + 0.25x
820 = 1.25x
820/1.25 = x
656 = x
Dealer's Cost of refrigeratior = $656
Mark up = 25% Cost Price
Selling Price = Cost Price + 25% Cost Price.
Let the cost price = x
Selling Price = x + 25% of x
820 = x + 0.25x
820 = 1.25x
820/1.25 = x
656 = x
Dealer's Cost of refrigeratior = $656
