PSLEEric bought one laptop for $272 after a discount of 20%.
- What was the price of the laptop before discount?
- He paid $114 for a computer. The total discount for the laptop and computer was $154. What was the percentage discount given for the computer?
(a)
Price of the laptop after the discount in percentage
= 100% - 20%
= 80%
80% of the price of the laptop = 272
1% of the price of the laptop = 272 ÷ 80 = 3.4
100% of the price of the laptop = 100 x 3.4 = 340
Price of the laptop before the discount = $340
(b)
Discount of the laptop
= 340 - 272
= $68
Discount of the computer
= 154 - 68
= $86
Original price of the computer
= 114 + 86
= $200
Percentage discount of the computer
=
86200 x 100%
= 43%
Answer(s): (a) $340; (b) 43%
