Answer:
47.5%
Explanation:
Data provided in the question:
Clearance discount percentage offered = 30%
Additional discount = 25%
Now,
Let the price of the car be $100
Therefore,
Price after the clearance discount = $100 - 30% of $100
= $100 - $30
= $70
Therefore,
Price after additional 25% discount = $70 - 25% of $70
= $70 - $17.5
= $52.5
Thus,
Total discount percentage
= [ ( Original cost - Selling cost ) ÷ Original cost] × 100%
= [ ( $100 - $52.5 ) ÷ $100 ] × 100%
= 47.5%
