SALEBuy 1 television set at 5% discount
Buy 2 or more television sets at 20% discount each
- Ken bought 1 television set. How much did he pay?
- What is the maximum number of television sets Ian can buy if he has $7000?
(a)
Discounted price of 1 television set in percent if only 1 was bought
= 100% - 5%
= 95%
100% of 1 television set = 1600
1% of 1 television set = 1600 ÷ 100 = 16
95% of 1 television set = 95 x 16 = 1520
Amount that Ken paid for 1 television set = $1520
(b)
Discounted price of 1 television set in percent if more than 1 was bought
= 100% - 20%
= 80%
80% of 1 television set = 80 x 16 = 1280
Amount that Ian paid for 1 television set = $1280
Maximum number of television sets that Ian can buy if he has $7000
= 7000 ÷ 1280
= 5 r 600
Answer(s): (a) $1520; (b) 5
