SALEBuy 1 printer at 20% discount
Buy 2 or more printers at 30% discount each
- Cole bought 1 printer. How much did he pay?
- What is the maximum number of printers Oscar can buy if he has $2000?
(a)
Discounted price of 1 printer in percent if only 1 was bought
= 100% - 20%
= 80%
100% of 1 printer = 1200
1% of 1 printer = 1200 ÷ 100 = 12
80% of 1 printer = 80 x 12 = 960
Amount that Cole paid for 1 printer = $960
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 30%
= 70%
70% of 1 printer = 70 x 12 = 840
Amount that Oscar paid for 1 printer = $840
Maximum number of printers that Oscar can buy if he has $2000
= 2000 ÷ 840
= 2 r 320
Answer(s): (a) $960; (b) 2
