Nick and Jack went to buy printers at a sale. The usual price of 1 printer was $600 each.
SALEBuy 1 printer at 15% discount
Buy 2 or more printers at 20% discount each
- Nick bought 1 printer. How much did he pay?
- What is the maximum number of printers Jack can buy if he has $4000?
(a)
Discounted price of 1 printer in percent if only 1 was bought
= 100% - 15%
= 85%
100% of 1 printer = 600
1% of 1 printer = 600 ÷ 100 = 6
85% of 1 printer = 85 x 6 = 510
Amount that Nick paid for 1 printer = $510
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 20%
= 80%
80% of 1 printer = 80 x 6 = 480
Amount that Jack paid for 1 printer = $480
Maximum number of printers that Jack can buy if he has $4000
= 4000 ÷ 480
= 8 r 160
Answer(s): (a) $510; (b) 8
