A furniture shop had a 10% discount storewide. The original price of a sofa was $1200.
- How much was the sofa after discount?
- Danny paid $2790 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 = 1200
1% of the price of the sofa = 1200 ÷ 100 = 12
90% of the price of the sofa = 90 x 12 = $1080
Price of the sofa after discount = $1080
(b)
Discounted price of the massage chair
= 2790 - 1080
= $1710
90% of the price of the massage chair = 1710
1% of the price of the massage chair = 1710 ÷ 90 = 19
100% of the price of the massage chair = 100 x 19 = 1900
Original price of the massage chair = $1900
Answer(s): (a) $1080; (b) $1900
