SALEBuy 1 printer at 15% discount
Buy 2 or more printers at 20% discount each
- Peter bought 1 printer. How much did he pay?
- What is the maximum number of printers Nick can buy if he has $5000?
(a)
Discounted price of 1 printer in percent if only 1 was bought
= 100% - 15%
= 85%
100% of 1 printer = 1400
1% of 1 printer = 1400 ÷ 100 = 14
85% of 1 printer = 85 x 14 = 1190
Amount that Peter paid for 1 printer = $1190
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 20%
= 80%
80% of 1 printer = 80 x 14 = 1120
Amount that Nick paid for 1 printer = $1120
Maximum number of printers that Nick can buy if he has $5000
= 5000 ÷ 1120
= 4 r 520
Answer(s): (a) $1190; (b) 4
