Step-by-step explanation:
The horizontal stretch or compression for a function f(x) is given by g = f(bx) where b is a constant. If b> 0 then the graph of a function is compressed.
As it is given in the question that the function is transformed by a compression factor of 3.
Given function
The value of k will be 3 if the function is transformed by a compression factor of 3
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
