PSLENick bought one hi-fi system for $240 after a discount of 25%.
- What was the price of the hi-fi system before discount?
- He paid $140 for a stereo system. The total discount for the hi-fi system and stereo system was $115. What was the percentage discount given for the stereo system?
(a)
Price of the hi-fi system after the discount in percentage
= 100% - 25%
= 75%
75% of the price of the hi-fi system = 240
1% of the price of the hi-fi system = 240 ÷ 75 = 3.2
100% of the price of the hi-fi system = 100 x 3.2 = 320
Price of the hi-fi system before the discount = $320
(b)
Discount of the hi-fi system
= 320 - 240
= $80
Discount of the stereo system
= 115 - 80
= $35
Original price of the stereo system
= 140 + 35
= $175
Percentage discount of the stereo system
=
35175 x 100%
= 20%
Answer(s): (a) $320; (b) 20%
