PSLESimon bought one stereo system for $198 after a discount of 25%.
- What was the price of the stereo system before discount?
- He paid $168 for a mobile phone. The total discount for the stereo system and mobile phone was $198. What was the percentage discount given for the mobile phone?
(a)
Price of the stereo system after the discount in percentage
= 100% - 25%
= 75%
75% of the price of the stereo system = 198
1% of the price of the stereo system = 198 ÷ 75 = 2.64
100% of the price of the stereo system = 100 x 2.64 = 264
Price of the stereo system before the discount = $264
(b)
Discount of the stereo system
= 264 - 198
= $66
Discount of the mobile phone
= 198 - 66
= $132
Original price of the mobile phone
= 168 + 132
= $300
Percentage discount of the mobile phone
=
132300 x 100%
= 44%
Answer(s): (a) $264; (b) 44%
