SALEBuy 1 tablet at 20% discount
Buy 2 or more tablets at 35% discount each
- Perry bought 1 tablet. How much did he pay?
- What is the maximum number of tablets Fabian can buy if he has $5000?
(a)
Discounted price of 1 tablet in percent if only 1 was bought
= 100% - 20%
= 80%
100% of 1 tablet = 1000
1% of 1 tablet = 1000 ÷ 100 = 10
80% of 1 tablet = 80 x 10 = 800
Amount that Perry paid for 1 tablet = $800
(b)
Discounted price of 1 tablet in percent if more than 1 was bought
= 100% - 35%
= 65%
65% of 1 tablet = 65 x 10 = 650
Amount that Fabian paid for 1 tablet = $650
Maximum number of tablets that Fabian can buy if he has $5000
= 5000 ÷ 650
= 7 r 450
Answer(s): (a) $800; (b) 7
