SALEBuy 1 tablet at 5% discount
Buy 2 or more tablets at 20% discount each
- Warren bought 1 tablet. How much did he pay?
- What is the maximum number of tablets Valen can buy if he has $2000?
(a)
Discounted price of 1 tablet in percent if only 1 was bought
= 100% - 5%
= 95%
100% of 1 tablet = 1800
1% of 1 tablet = 1800 ÷ 100 = 18
95% of 1 tablet = 95 x 18 = 1710
Amount that Warren paid for 1 tablet = $1710
(b)
Discounted price of 1 tablet in percent if more than 1 was bought
= 100% - 20%
= 80%
80% of 1 tablet = 80 x 18 = 1440
Amount that Valen paid for 1 tablet = $1440
Maximum number of tablets that Valen can buy if he has $2000
= 2000 ÷ 1440
= 1 r 560
Answer(s): (a) $1710; (b) 1
