SALEBuy 1 television set at 20% discount
Buy 2 or more television sets at 30% discount each
- Fred bought 1 television set. How much did he pay?
- What is the maximum number of television sets Pierre can buy if he has $4000?
(a)
Discounted price of 1 television set in percent if only 1 was bought
= 100% - 20%
= 80%
100% of 1 television set = 1200
1% of 1 television set = 1200 ÷ 100 = 12
80% of 1 television set = 80 x 12 = 960
Amount that Fred paid for 1 television set = $960
(b)
Discounted price of 1 television set in percent if more than 1 was bought
= 100% - 30%
= 70%
70% of 1 television set = 70 x 12 = 840
Amount that Pierre paid for 1 television set = $840
Maximum number of television sets that Pierre can buy if he has $4000
= 4000 ÷ 840
= 4 r 640
Answer(s): (a) $960; (b) 4
