SALEBuy 1 printer at 15% discount
Buy 2 or more printers at 30% discount each
- Fred bought 1 printer. How much did he pay?
- What is the maximum number of printers Carl 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 = 300
1% of 1 printer = 300 ÷ 100 = 3
85% of 1 printer = 85 x 3 = 255
Amount that Fred paid for 1 printer = $255
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 30%
= 70%
70% of 1 printer = 70 x 3 = 210
Amount that Carl paid for 1 printer = $210
Maximum number of printers that Carl can buy if he has $5000
= 5000 ÷ 210
= 23 r 170
Answer(s): (a) $255; (b) 23
