The selling price of a refrigerator is $584. if the markup is 25% of the dealers cost, what is the dealers cost of the refrigerator? (the markup is the amount added to the dealers cost of an item to arrive at the selling price of that item) i need step by step

Selling price of the refrigerator = $584
Percentage of markup of the dealers cost = 25%
Let us assume the dealers cost of the refrigerator = x
Then
125x/100 = 584
125x = 58400
x = 467.20

From the above deduction, it can be concluded that the dealers cost of the refrigerator was $467.20. I hope that the procedure is clear enough for you to understand.

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a
