A furniture shop had a 10% discount storewide. The original price of a sofa was $1700.
- How much was the sofa after discount?
- Danny paid $2160 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 = 1700
1% of the price of the sofa = 1700 ÷ 100 = 17
90% of the price of the sofa = 90 x 17 = $1530
Price of the sofa after discount = $1530
(b)
Discounted price of the massage chair
= 2160 - 1530
= $630
90% of the price of the massage chair = 630
1% of the price of the massage chair = 630 ÷ 90 = 7
100% of the price of the massage chair = 100 x 7 = 700
Original price of the massage chair = $700
Answer(s): (a) $1530; (b) $700
