SALEBuy 1 tablet at 15% discount
Buy 2 or more tablets at 30% discount each
- Henry bought 1 tablet. How much did he pay?
- What is the maximum number of tablets Mark can buy if he has $6000?
(a)
Discounted price of 1 tablet in percent if only 1 was bought
= 100% - 15%
= 85%
100% of 1 tablet = 1800
1% of 1 tablet = 1800 ÷ 100 = 18
85% of 1 tablet = 85 x 18 = 1530
Amount that Henry paid for 1 tablet = $1530
(b)
Discounted price of 1 tablet in percent if more than 1 was bought
= 100% - 30%
= 70%
70% of 1 tablet = 70 x 18 = 1260
Amount that Mark paid for 1 tablet = $1260
Maximum number of tablets that Mark can buy if he has $6000
= 6000 ÷ 1260
= 4 r 960
Answer(s): (a) $1530; (b) 4
