Assuming the question asks for the discout amount:
To find the discount percentage, you would basically:
• find the lessened amount from original
,
• take that amount, divide by original
,
• multiply that decimal by 100 to get the percentage discount
Lessened amount = 721.24 - 576.99 = $144.25
Now, discount (in decimal):
144.25/721.24 = 0.20
0.20 * 100 = 20
The discount is 20%
