SALEBuy 1 tablet at 10% discount
Buy 2 or more tablets at 15% discount each
- Oliver bought 1 tablet. How much did he pay?
- What is the maximum number of tablets Warren can buy if he has $2000?
(a)
Discounted price of 1 tablet in percent if only 1 was bought
= 100% - 10%
= 90%
100% of 1 tablet = 700
1% of 1 tablet = 700 ÷ 100 = 7
90% of 1 tablet = 90 x 7 = 630
Amount that Oliver paid for 1 tablet = $630
(b)
Discounted price of 1 tablet in percent if more than 1 was bought
= 100% - 15%
= 85%
85% of 1 tablet = 85 x 7 = 595
Amount that Warren paid for 1 tablet = $595
Maximum number of tablets that Warren can buy if he has $2000
= 2000 ÷ 595
= 3 r 215
Answer(s): (a) $630; (b) 3
