Tom and Simon 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 30% discount each
- Tom bought 1 printer. How much did he pay?
- What is the maximum number of printers Simon can buy if he has $6000?
(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 Tom paid for 1 printer = $510
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 30%
= 70%
70% of 1 printer = 70 x 6 = 420
Amount that Simon paid for 1 printer = $420
Maximum number of printers that Simon can buy if he has $6000
= 6000 ÷ 420
= 14 r 120
Answer(s): (a) $510; (b) 14
