Answer:
The sale price has a 45% discount.
Explanation:
Reviewing the information given to solve the question, we have:
Regular price of cell phone ring tones collection = US$ 18.80
Sale price of cell phone ring tones collection = US$ 10.34
For finding the discount percentage, we do the following operation:
Discount percentage = 1 - (Sale price/Regular price)
Discount percentage = 1 - (10.34/18.80)
Discount percentage = 1 - 0.55
Discount percentage = 0.45
Discount percentage = 0.45 * 100 = 45%
The sale price has a 45% discount.
