Sam and Harry went to buy projectors at a sale. The usual price of 1 projector was $2000 each.
SALEBuy 1 projector at 5% discount
Buy 2 or more projectors at 15% discount each
- Sam bought 1 projector. How much did he pay?
- What is the maximum number of projectors Harry can buy if he has $8000?
(a)
Discounted price of 1 projector in percent if only 1 was bought
= 100% - 5%
= 95%
100% of 1 projector = 2000
1% of 1 projector = 2000 ÷ 100 = 20
95% of 1 projector = 95 x 20 = 1900
Amount that Sam paid for 1 projector = $1900
(b)
Discounted price of 1 projector in percent if more than 1 was bought
= 100% - 15%
= 85%
85% of 1 projector = 85 x 20 = 1700
Amount that Harry paid for 1 projector = $1700
Maximum number of projectors that Harry can buy if he has $8000
= 8000 ÷ 1700
= 4 r 1200
Answer(s): (a) $1900; (b) 4
