SALEBuy 1 tablet at 20% discount
Buy 2 or more tablets at 30% discount each
- Cody bought 1 tablet. How much did he pay?
- What is the maximum number of tablets Carl can buy if he has $6000?
(a)
Discounted price of 1 tablet in percent if only 1 was bought
= 100% - 20%
= 80%
100% of 1 tablet = 200
1% of 1 tablet = 200 ÷ 100 = 2
80% of 1 tablet = 80 x 2 = 160
Amount that Cody paid for 1 tablet = $160
(b)
Discounted price of 1 tablet in percent if more than 1 was bought
= 100% - 30%
= 70%
70% of 1 tablet = 70 x 2 = 140
Amount that Carl paid for 1 tablet = $140
Maximum number of tablets that Carl can buy if he has $6000
= 6000 ÷ 140
= 42 r 120
Answer(s): (a) $160; (b) 42
