SALEBuy 1 printer at 10% discount
Buy 2 or more printers at 20% discount each
- Brandon bought 1 printer. How much did he pay?
- What is the maximum number of printers Bobby can buy if he has $6000?
(a)
Discounted price of 1 printer in percent if only 1 was bought
= 100% - 10%
= 90%
100% of 1 printer = 400
1% of 1 printer = 400 ÷ 100 = 4
90% of 1 printer = 90 x 4 = 360
Amount that Brandon paid for 1 printer = $360
(b)
Discounted price of 1 printer in percent if more than 1 was bought
= 100% - 20%
= 80%
80% of 1 printer = 80 x 4 = 320
Amount that Bobby paid for 1 printer = $320
Maximum number of printers that Bobby can buy if he has $6000
= 6000 ÷ 320
= 18 r 240
Answer(s): (a) $360; (b) 18
