SALEBuy 1 printer at 5% discount
Buy 2 or more printers at 10% discount each
- Mark bought 1 printer. How much did he pay?
- What is the maximum number of printers Vaidev can buy if he has $3000?
(a)
Discounted price of 1 printer in percent if only 1 was bought
= 100% - 5%
= 95%
100% of 1 printer = 400
1% of 1 printer = 400 ÷ 100 = 4
95% of 1 printer = 95 x 4 = 380
Amount that Mark paid for 1 printer = $380
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 10%
= 90%
90% of 1 printer = 90 x 4 = 360
Amount that Vaidev paid for 1 printer = $360
Maximum number of printers that Vaidev can buy if he has $3000
= 3000 ÷ 360
= 8 r 120
Answer(s): (a) $380; (b) 8
