SALEBuy 1 hard drive at 20% discount
Buy 2 or more hard drives at 35% discount each
- Gabriel bought 1 hard drive. How much did he pay?
- What is the maximum number of hard drives Rael can buy if he has $4000?
(a)
Discounted price of 1 hard drive in percent if only 1 was bought
= 100% - 20%
= 80%
100% of 1 hard drive = 1000
1% of 1 hard drive = 1000 ÷ 100 = 10
80% of 1 hard drive = 80 x 10 = 800
Amount that Gabriel paid for 1 hard drive = $800
(b)
Discounted price of 1 hard drive in percent if more than 1 was bought
= 100% - 35%
= 65%
65% of 1 hard drive = 65 x 10 = 650
Amount that Rael paid for 1 hard drive = $650
Maximum number of hard drives that Rael can buy if he has $4000
= 4000 ÷ 650
= 6 r 100
Answer(s): (a) $800; (b) 6
