Answer:
CEO earns $31,045.5
Step-by-step explanation:
Price of each product = $855
Number of product sold = 250
Total revenue = price × quantity
= 855 × 250
= $213,750
Total expenditure = $6,780
Profits = Total revenue - Total expenditure
= 213,750 - 6,780
= $206,970
Profits = $206,970
The CEO of the company earns 15% of this profit
Amount CEO earns = 15% of $206,970
= 15/100 × 206,970
= 0.15 × 206,970
= $31,045.5
CEO earns $31,045.5
