Answer:
To determine which discount is cheaper for a $56 item, we need to calculate the actual discount amount of each option.
A discount of $5 off means the new price would be $56 - $5 = $51.
A discount of 15% off means the discount amount is: 15% x $56 = $8.40. Therefore, the new price would be $56 - $8.40 = $47.60.
So the discount of 15% off is cheaper for a $56 item compared to a $5.
