The dealers cost of the refrigerator is $591.36
<h3>How to determine the dealer cost</h3>
Represent the dealer cost of the refrigerator with x.
Given that the markup is 20% and the selling price of the refrigerator is $739.20, then we have the following equation

Evaluate the product
x = 591.36
Hence, the dealers cost of the refrigerator is $591.36
