PSLENeave bought one projector for $150 after a discount of 25%.
- What was the price of the projector before discount?
- He paid $122 for a stereo system. The total discount for the projector and stereo system was $172. What was the percentage discount given for the stereo system?
(a)
Price of the projector after the discount in percentage
= 100% - 25%
= 75%
75% of the price of the projector = 150
1% of the price of the projector = 150 ÷ 75 = 2
100% of the price of the projector = 100 x 2 = 200
Price of the projector before the discount = $200
(b)
Discount of the projector
= 200 - 150
= $50
Discount of the stereo system
= 172 - 50
= $122
Original price of the stereo system
= 122 + 122
= $244
Percentage discount of the stereo system
=
122244 x 100%
= 50%
Answer(s): (a) $200; (b) 50%
