Question

take 10% of $85
b.
take 10% of $90
c.
take 15% of $85
d.
take 25% of $100

Answer 1

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
