PSLEEthan bought one hi-fi system for $259 after a discount of 30%.
- What was the price of the hi-fi system before discount?
- He paid $196 for a printer. The total discount for the hi-fi system and printer was $195. What was the percentage discount given for the printer?
(a)
Price of the hi-fi system after the discount in percentage
= 100% - 30%
= 70%
70% of the price of the hi-fi system = 259
1% of the price of the hi-fi system = 259 ÷ 70 = 3.7
100% of the price of the hi-fi system = 100 x 3.7 = 370
Price of the hi-fi system before the discount = $370
(b)
Discount of the hi-fi system
= 370 - 259
= $111
Discount of the printer
= 195 - 111
= $84
Original price of the printer
= 196 + 84
= $280
Percentage discount of the printer
=
84280 x 100%
= 30%
Answer(s): (a) $370; (b) 30%
