Answer:
30% discount
Explanation:
Given that,
the sale price of sofa larry and dona bought = 1,344
the original price of sofa before discount = 1,920
Discount rate Calculation
Discount = Marked Price - Selling Price
Discount = 1920 - 1344
Discount = 576
Discount percentage = Discount/Marked Price × 100%
Discount percentage = 576 / 1920 × 100%
Discount percentage = 3/10 × 100%
Discount percentage = 30%
So, the discount rate on sofa which larry and dona bought is 30%
