SALEBuy 1 massage chair at 20% discount
Buy 2 or more massage chairs at 35% discount each
- Jeremy bought 1 massage chair. How much did he pay?
- What is the maximum number of massage chairs Ken can buy if he has $3000?
(a)
Discounted price of 1 massage chair in percent if only 1 was bought
= 100% - 20%
= 80%
100% of 1 massage chair = 300
1% of 1 massage chair = 300 ÷ 100 = 3
80% of 1 massage chair = 80 x 3 = 240
Amount that Jeremy paid for 1 massage chair = $240
(b)
Discounted price of 1 massage chair in percent if more than 1 was bought
= 100% - 35%
= 65%
65% of 1 massage chair = 65 x 3 = 195
Amount that Ken paid for 1 massage chair = $195
Maximum number of massage chairs that Ken can buy if he has $3000
= 3000 ÷ 195
= 15 r 75
Answer(s): (a) $240; (b) 15
