The sale price has a 45% discount.

Step-by-step 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.
