Step-by-step explanation:

The expression is 7x-2y-1.

If x=3, then you multiply 3 and 7.

7x3=21.

21-2y-1

If y=4, then you multiply 4 and 2.

4x2=8.

21-8-1

Then you combine like terms.

Mark up percentages are used to increase the prices of items

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
