SALEBuy 1 tablet at 15% discount
Buy 2 or more tablets at 30% discount each
- Liam bought 1 tablet. How much did he pay?
- What is the maximum number of tablets Elijah can buy if he has $8000?
(a)
Discounted price of 1 tablet in percent if only 1 was bought
= 100% - 15%
= 85%
100% of 1 tablet = 1500
1% of 1 tablet = 1500 ÷ 100 = 15
85% of 1 tablet = 85 x 15 = 1275
Amount that Liam paid for 1 tablet = $1275
(b)
Discounted price of 1 tablet in percent if more than 1 was bought
= 100% - 30%
= 70%
70% of 1 tablet = 70 x 15 = 1050
Amount that Elijah paid for 1 tablet = $1050
Maximum number of tablets that Elijah can buy if he has $8000
= 8000 ÷ 1050
= 7 r 650
Answer(s): (a) $1275; (b) 7
