Valen and Ian went to buy printers at a sale. The usual price of 1 printer was $700 each.
SALEBuy 1 printer at 5% discount
Buy 2 or more printers at 20% discount each
- Valen bought 1 printer. How much did he pay?
- What is the maximum number of printers Ian 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 = 700
1% of 1 printer = 700 ÷ 100 = 7
95% of 1 printer = 95 x 7 = 665
Amount that Valen paid for 1 printer = $665
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 20%
= 80%
80% of 1 printer = 80 x 7 = 560
Amount that Ian paid for 1 printer = $560
Maximum number of printers that Ian can buy if he has $3000
= 3000 ÷ 560
= 5 r 200
Answer(s): (a) $665; (b) 5
