Answer: 5%
Step-by-step explanation: In order to calculate the percentage of the discount we need to first calculate the amount of the discount.

In order to calculate the percentage of the discount you must divide the discount amount by the original cost.
$2.36 / $47.26 = .0499 = rounded off to a 5% discount
