PSLEOliver bought one printer for $225 after a discount of 10%.
- What was the price of the printer before discount?
- He paid $159 for a projector. The total discount for the printer and projector was $184. What was the percentage discount given for the projector?
(a)
Price of the printer after the discount in percentage
= 100% - 10%
= 90%
90% of the price of the printer = 225
1% of the price of the printer = 225 ÷ 90 = 2.5
100% of the price of the printer = 100 x 2.5 = 250
Price of the printer before the discount = $250
(b)
Discount of the printer
= 250 - 225
= $25
Discount of the projector
= 184 - 25
= $159
Original price of the projector
= 159 + 159
= $318
Percentage discount of the projector
=
159318 x 100%
= 50%
Answer(s): (a) $250; (b) 50%
