SALEBuy 1 printer at 10% discount
Buy 2 or more printers at 15% discount each
- Oscar bought 1 printer. How much did he pay?
- What is the maximum number of printers Jeremy can buy if he has $5000?
(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 Oscar paid for 1 printer = $1710
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 15%
= 85%
85% of 1 printer = 85 x 19 = 1615
Amount that Jeremy paid for 1 printer = $1615
Maximum number of printers that Jeremy can buy if he has $5000
= 5000 ÷ 1615
= 3 r 155
Answer(s): (a) $1710; (b) 3
