PSLEJenson bought one printer for $171 after a discount of 25%.
- What was the price of the printer before discount?
- He paid $136 for a stereo system. The total discount for the printer and stereo system was $193. What was the percentage discount given for the stereo system?
(a)
Price of the printer after the discount in percentage
= 100% - 25%
= 75%
75% of the price of the printer = 171
1% of the price of the printer = 171 ÷ 75 = 2.28
100% of the price of the printer = 100 x 2.28 = 228
Price of the printer before the discount = $228
(b)
Discount of the printer
= 228 - 171
= $57
Discount of the stereo system
= 193 - 57
= $136
Original price of the stereo system
= 136 + 136
= $272
Percentage discount of the stereo system
=
136272 x 100%
= 50%
Answer(s): (a) $228; (b) 50%
