SALEBuy 1 printer at 15% discount
Buy 2 or more printers at 25% discount each
- Zeph bought 1 printer. How much did he pay?
- What is the maximum number of printers Albert can buy if he has $2000?
(a)
Discounted price of 1 printer in percent if only 1 was bought
= 100% - 15%
= 85%
100% of 1 printer = 1700
1% of 1 printer = 1700 ÷ 100 = 17
85% of 1 printer = 85 x 17 = 1445
Amount that Zeph paid for 1 printer = $1445
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 25%
= 75%
75% of 1 printer = 75 x 17 = 1275
Amount that Albert paid for 1 printer = $1275
Maximum number of printers that Albert can buy if he has $2000
= 2000 ÷ 1275
= 1 r 725
Answer(s): (a) $1445; (b) 1
