Ken and Dylan went to buy projectors at a sale. The usual price of 1 projector was $200 each.
SALEBuy 1 projector at 15% discount
Buy 2 or more projectors at 30% discount each
- Ken bought 1 projector. How much did he pay?
- What is the maximum number of projectors Dylan can buy if he has $8000?
(a)
Discounted price of 1 projector in percent if only 1 was bought
= 100% - 15%
= 85%
100% of 1 projector = 200
1% of 1 projector = 200 ÷ 100 = 2
85% of 1 projector = 85 x 2 = 170
Amount that Ken paid for 1 projector = $170
(b)
Discounted price of 1 projector in percent if more than 1 was bought
= 100% - 30%
= 70%
70% of 1 projector = 70 x 2 = 140
Amount that Dylan paid for 1 projector = $140
Maximum number of projectors that Dylan can buy if he has $8000
= 8000 ÷ 140
= 57 r 20
Answer(s): (a) $170; (b) 57
