SALEBuy 1 television set at 5% discount
Buy 2 or more television sets at 15% discount each
- Liam bought 1 television set. How much did he pay?
- What is the maximum number of television sets Seth 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 = 300
1% of 1 television set = 300 ÷ 100 = 3
95% of 1 television set = 95 x 3 = 285
Amount that Liam paid for 1 television set = $285
(b)
Discounted price of 1 television set in percent if more than 1 was bought
= 100% - 15%
= 85%
85% of 1 television set = 85 x 3 = 255
Amount that Seth paid for 1 television set = $255
Maximum number of television sets that Seth can buy if he has $7000
= 7000 ÷ 255
= 27 r 115
Answer(s): (a) $285; (b) 27
