SALEBuy 1 laptop at 15% discount
Buy 2 or more laptops at 20% discount each
- Asher bought 1 laptop. How much did he pay?
- What is the maximum number of laptops Cody can buy if he has $8000?
(a)
Discounted price of 1 laptop in percent if only 1 was bought
= 100% - 15%
= 85%
100% of 1 laptop = 300
1% of 1 laptop = 300 ÷ 100 = 3
85% of 1 laptop = 85 x 3 = 255
Amount that Asher paid for 1 laptop = $255
(b)
Discounted price of 1 laptop in percent if more than 1 was bought
= 100% - 20%
= 80%
80% of 1 laptop = 80 x 3 = 240
Amount that Cody paid for 1 laptop = $240
Maximum number of laptops that Cody can buy if he has $8000
= 8000 ÷ 240
= 33 r 80
Answer(s): (a) $255; (b) 33
