A furniture shop had a 10% discount storewide. The original price of a sofa was $2100.
- How much was the sofa after discount?
- Danny paid $3510 for a sofa and a massage chair. What was the original price of the massage chair?
(a)
Discounted price of the sofa in percent
= 100% - 10%
= 90%
100% of the price of the sofa = 2100
1% of the price of the sofa = 2100 ÷ 100 = 21
90% of the price of the sofa = 90 x 21 = $1890
Price of the sofa after discount = $1890
(b)
Discounted price of the massage chair
= 3510 - 1890
= $1620
90% of the price of the massage chair = 1620
1% of the price of the massage chair = 1620 ÷ 90 = 18
100% of the price of the massage chair = 100 x 18 = 1800
Original price of the massage chair = $1800
Answer(s): (a) $1890; (b) $1800
