Answer:
10151
Step-by-step explanation:
You want to know the number of items costing 2.16 that must be sold for 3.49 to recover an investment of 5000 and make a profit of 8500. (Amounts in dollars.)
The contribution margin of each item is ...
3.49 -2.16 = 1.33
The total wanted from sales is ...
5000 +8500 = 13,500
Then the number that must be sold is ...
13500/(1.33/item) = 10,150.38 items ≈ 10151 items
About 10,151 items must be sold to make a profit of 8500 dollars.
