SALEBuy 1 television set at 10% discount
Buy 2 or more television sets at 25% discount each
- Peter bought 1 television set. How much did he pay?
- What is the maximum number of television sets Cody can buy if he has $4000?
(a)
Discounted price of 1 television set in percent if only 1 was bought
= 100% - 10%
= 90%
100% of 1 television set = 200
1% of 1 television set = 200 ÷ 100 = 2
90% of 1 television set = 90 x 2 = 180
Amount that Peter paid for 1 television set = $180
(b)
Discounted price of 1 television set in percent if more than 1 was bought
= 100% - 25%
= 75%
75% of 1 television set = 75 x 2 = 150
Amount that Cody paid for 1 television set = $150
Maximum number of television sets that Cody can buy if he has $4000
= 4000 ÷ 150
= 26 r 100
Answer(s): (a) $180; (b) 26
