PSLEZane bought one projector for $182 after a discount of 30%.
- What was the price of the projector before discount?
- He paid $123 for a stereo system. The total discount for the projector and stereo system was $160. What was the percentage discount given for the stereo system?
(a)
Price of the projector after the discount in percentage
= 100% - 30%
= 70%
70% of the price of the projector = 182
1% of the price of the projector = 182 ÷ 70 = 2.6
100% of the price of the projector = 100 x 2.6 = 260
Price of the projector before the discount = $260
(b)
Discount of the projector
= 260 - 182
= $78
Discount of the stereo system
= 160 - 78
= $82
Original price of the stereo system
= 123 + 82
= $205
Percentage discount of the stereo system
=
82205 x 100%
= 40%
Answer(s): (a) $260; (b) 40%
