Oscar purchased a new hat that was on sale for $5.06. The original price was $9.20. What percentage discount was the sale price?​

45%

Step-by-step explanation:

Discount = original price - selling price

= $9.20 - $5.06

Discount = $4.14

Discount Percent = discount x 100 / original price

= $4.14 x 100 / $9.20

= $414 / $9.20

Therefore,

Discount Percent = 45%
