PSLEGabriel bought one printer for $180 after a discount of 10%.
- What was the price of the printer before discount?
- He paid $138 for a projector. The total discount for the printer and projector was $112. 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 = 180
1% of the price of the printer = 180 ÷ 90 = 2
100% of the price of the printer = 100 x 2 = 200
Price of the printer before the discount = $200
(b)
Discount of the printer
= 200 - 180
= $20
Discount of the projector
= 112 - 20
= $92
Original price of the projector
= 138 + 92
= $230
Percentage discount of the projector
=
92230 x 100%
= 40%
Answer(s): (a) $200; (b) 40%
