Because B is the midpoint of AC and AB = 2x + 4, BC must also be 2x + 4. So you add 2x + 4 to 2x + 4 to get 4x + 8. Then you set that to be equal to 40. Then you subtract 8 from both sides to get 4x = 32 and divide by 4 so you end up with x = 8.

Lisa [10]

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

x = 739.20 * (1 - 20%)

Evaluate the product

x = 591.36

Hence, the dealers cost of the refrigerator is $591.36
