Simon and Warren went to buy projectors at a sale. The usual price of 1 projector was $1500 each.
SALEBuy 1 projector at 5% discount
Buy 2 or more projectors at 20% discount each
- Simon bought 1 projector. How much did he pay?
- What is the maximum number of projectors Warren can buy if he has $5000?
(a)
Discounted price of 1 projector in percent if only 1 was bought
= 100% - 5%
= 95%
100% of 1 projector = 1500
1% of 1 projector = 1500 ÷ 100 = 15
95% of 1 projector = 95 x 15 = 1425
Amount that Simon paid for 1 projector = $1425
(b)
Discounted price of 1 projector in percent if more than 1 was bought
= 100% - 20%
= 80%
80% of 1 projector = 80 x 15 = 1200
Amount that Warren paid for 1 projector = $1200
Maximum number of projectors that Warren can buy if he has $5000
= 5000 ÷ 1200
= 4 r 200
Answer(s): (a) $1425; (b) 4
