SALEBuy 1 printer at 5% discount
Buy 2 or more printers at 10% discount each
- Jack bought 1 printer. How much did he pay?
- What is the maximum number of printers Cody can buy if he has $7000?
(a)
Discounted price of 1 printer in percent if only 1 was bought
= 100% - 5%
= 95%
100% of 1 printer = 1800
1% of 1 printer = 1800 ÷ 100 = 18
95% of 1 printer = 95 x 18 = 1710
Amount that Jack paid for 1 printer = $1710
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 10%
= 90%
90% of 1 printer = 90 x 18 = 1620
Amount that Cody paid for 1 printer = $1620
Maximum number of printers that Cody can buy if he has $7000
= 7000 ÷ 1620
= 4 r 520
Answer(s): (a) $1710; (b) 4
