Answer:
32%
Explanation:
The percentage profit is the ratio of profit to original cost, expressed as a percentage. The profit is the difference between the selling price and the cost.
profit = selling price - cost
profit = $6600 -5000 = $1600
The ratio of that to cost is ...
$1600/$5000 = 0.32
As a percentage, that is ...
0.32 × 100% = 32%
The car dealer's profit was 32% of his cost.
