the selling price of a refrigerator, is $678.30. if the markup is 5% of the dealers cost, what is the dealers cost of the refrigerator? $\\square$
Answer
Explanation:
Step1: Define variables for cost
Let ( C ) = dealer's cost.
Step2: Set up selling price equation
Selling price = Cost + 5% of cost: ( 678.30 = C + 0.05C )
Step3: Combine like terms
Simplify the right-hand side: ( 678.30 = 1.05C )
Step4: Solve for ( C )
Divide both sides by 1.05: ( C = \frac{678.30}{1.05} )
Answer:
$646.00
