Bobby and Asher went to buy computers at a sale. The usual price of 1 computer was $200 each.
SALEBuy 1 computer at 5% discount
Buy 2 or more computers at 15% discount each
- Bobby bought 1 computer. How much did he pay?
- What is the maximum number of computers Asher can buy if he has $6000?
(a)
Discounted price of 1 computer in percent if only 1 was bought
= 100% - 5%
= 95%
100% of 1 computer = 200
1% of 1 computer = 200 ÷ 100 = 2
95% of 1 computer = 95 x 2 = 190
Amount that Bobby paid for 1 computer = $190
(b)
Discounted price of 1 computer in percent if more than 1 was bought
= 100% - 15%
= 85%
85% of 1 computer = 85 x 2 = 170
Amount that Asher paid for 1 computer = $170
Maximum number of computers that Asher can buy if he has $6000
= 6000 ÷ 170
= 35 r 50
Answer(s): (a) $190; (b) 35
