SALEBuy 1 tablet at 15% discount
Buy 2 or more tablets at 25% discount each
- Charlie bought 1 tablet. How much did he pay?
- What is the maximum number of tablets Ahmad 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 = 1500
1% of 1 tablet = 1500 ÷ 100 = 15
85% of 1 tablet = 85 x 15 = 1275
Amount that Charlie paid for 1 tablet = $1275
(b)
Discounted price of 1 tablet in percent if more than 1 was bought
= 100% - 25%
= 75%
75% of 1 tablet = 75 x 15 = 1125
Amount that Ahmad paid for 1 tablet = $1125
Maximum number of tablets that Ahmad can buy if he has $6000
= 6000 ÷ 1125
= 5 r 375
Answer(s): (a) $1275; (b) 5
