Answer:
The selling price would be $80
Step-by-step explanation:
Gross profit ratio is defined as the ratio of gross (total) profit divided by the gross (total) sales. If the profit is $100 on sales of $500, the gross profit ratio would be ($100/$500) or 0.25. This is usually expressed as a percentage, or 25%.
We can write this as Profit Ratio = (Profit)/(Sales)
In this case, we are given the cost ($60) and a profit ratio of 25% (or 0.25). Lets recognize that profit is equal to the sales minus the costs:
Profit = Sales - Cost.
Profit Ratio = (Profit)/(Sales)
Profit Ratio = (Sales - Cost)/(Sales)
0.25 = (Sales - $60)/(Sales)
0.25*(Sales) = (Sales - $60)
0.25*Sales = Sales - $60
-0.75Sales = -$60
Sales = $80
