SALEBuy 1 printer at 10% discount
Buy 2 or more printers at 20% discount each
- Gabriel bought 1 printer. How much did he pay?
- What is the maximum number of printers John can buy if he has $6000?
(a)
Discounted price of 1 printer in percent if only 1 was bought
= 100% - 10%
= 90%
100% of 1 printer = 200
1% of 1 printer = 200 ÷ 100 = 2
90% of 1 printer = 90 x 2 = 180
Amount that Gabriel paid for 1 printer = $180
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 20%
= 80%
80% of 1 printer = 80 x 2 = 160
Amount that John paid for 1 printer = $160
Maximum number of printers that John can buy if he has $6000
= 6000 ÷ 160
= 37 r 80
Answer(s): (a) $180; (b) 37
