PSLEJustin bought one laptop for $256 after a discount of 20%.
- What was the price of the laptop before discount?
- He paid $129 for a tablet. The total discount for the laptop and tablet was $150. What was the percentage discount given for the tablet?
(a)
Price of the laptop after the discount in percentage
= 100% - 20%
= 80%
80% of the price of the laptop = 256
1% of the price of the laptop = 256 ÷ 80 = 3.2
100% of the price of the laptop = 100 x 3.2 = 320
Price of the laptop before the discount = $320
(b)
Discount of the laptop
= 320 - 256
= $64
Discount of the tablet
= 150 - 64
= $86
Original price of the tablet
= 129 + 86
= $215
Percentage discount of the tablet
=
86215 x 100%
= 40%
Answer(s): (a) $320; (b) 40%
