SALEBuy 1 printer at 10% discount
Buy 2 or more printers at 20% discount each
- Oliver bought 1 printer. How much did he pay?
- What is the maximum number of printers Xavier can buy if he has $7000?
(a)
Discounted price of 1 printer in percent if only 1 was bought
= 100% - 10%
= 90%
100% of 1 printer = 1900
1% of 1 printer = 1900 ÷ 100 = 19
90% of 1 printer = 90 x 19 = 1710
Amount that Oliver paid for 1 printer = $1710
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 20%
= 80%
80% of 1 printer = 80 x 19 = 1520
Amount that Xavier paid for 1 printer = $1520
Maximum number of printers that Xavier can buy if he has $7000
= 7000 ÷ 1520
= 4 r 920
Answer(s): (a) $1710; (b) 4
