PSLETom bought one hi-fi system for $276 after a discount of 25%.
- What was the price of the hi-fi system before discount?
- He paid $198 for a printer. The total discount for the hi-fi system and printer was $194. What was the percentage discount given for the printer?
(a)
Price of the hi-fi system after the discount in percentage
= 100% - 25%
= 75%
75% of the price of the hi-fi system = 276
1% of the price of the hi-fi system = 276 ÷ 75 = 3.68
100% of the price of the hi-fi system = 100 x 3.68 = 368
Price of the hi-fi system before the discount = $368
(b)
Discount of the hi-fi system
= 368 - 276
= $92
Discount of the printer
= 194 - 92
= $102
Original price of the printer
= 198 + 102
= $300
Percentage discount of the printer
=
102300 x 100%
= 34%
Answer(s): (a) $368; (b) 34%
