Julian and Warren went to buy projectors at a sale. The usual price of 1 projector was $1400 each.
SALEBuy 1 projector at 20% discount
Buy 2 or more projectors at 25% discount each
- Julian bought 1 projector. How much did he pay?
- What is the maximum number of projectors Warren can buy if he has $2000?
(a)
Discounted price of 1 projector in percent if only 1 was bought
= 100% - 20%
= 80%
100% of 1 projector = 1400
1% of 1 projector = 1400 ÷ 100 = 14
80% of 1 projector = 80 x 14 = 1120
Amount that Julian paid for 1 projector = $1120
(b)
Discounted price of 1 projector in percent if more than 1 was bought
= 100% - 25%
= 75%
75% of 1 projector = 75 x 14 = 1050
Amount that Warren paid for 1 projector = $1050
Maximum number of projectors that Warren can buy if he has $2000
= 2000 ÷ 1050
= 1 r 950
Answer(s): (a) $1120; (b) 1
