SALEBuy 1 hard drive at 10% discount
Buy 2 or more hard drives at 25% discount each
- Ben bought 1 hard drive. How much did he pay?
- What is the maximum number of hard drives Wesley can buy if he has $5000?
(a)
Discounted price of 1 hard drive in percent if only 1 was bought
= 100% - 10%
= 90%
100% of 1 hard drive = 1100
1% of 1 hard drive = 1100 ÷ 100 = 11
90% of 1 hard drive = 90 x 11 = 990
Amount that Ben paid for 1 hard drive = $990
(b)
Discounted price of 1 hard drive in percent if more than 1 was bought
= 100% - 25%
= 75%
75% of 1 hard drive = 75 x 11 = 825
Amount that Wesley paid for 1 hard drive = $825
Maximum number of hard drives that Wesley can buy if he has $5000
= 5000 ÷ 825
= 6 r 50
Answer(s): (a) $990; (b) 6
