To calculate the successive discounts of 15% and 10% on a $100 item, you first apply the 15% discount and then the 10% discount to the new price.
1. Calculate the first discount of 15% on $100:
- 15% of $100 = $15
- New price after the first discount = $100 - $15 = $85
2. Next, apply the 10% discount on the new price of $85:
- 10% of $85 = $8.50
- Final price after both discounts = $85 - $8.50 = $76.50
Based on the choices provided, you take 10% of $85 (the price after the first discount). Therefore, the correct answer is:
**a. take 10% of $85**
