PSLECharlie bought one hard drive for $171 after a discount of 25%.
- What was the price of the hard drive before discount?
- He paid $126 for a laptop. The total discount for the hard drive and laptop was $156. What was the percentage discount given for the laptop?
(a)
Price of the hard drive after the discount in percentage
= 100% - 25%
= 75%
75% of the price of the hard drive = 171
1% of the price of the hard drive = 171 ÷ 75 = 2.28
100% of the price of the hard drive = 100 x 2.28 = 228
Price of the hard drive before the discount = $228
(b)
Discount of the hard drive
= 228 - 171
= $57
Discount of the laptop
= 156 - 57
= $99
Original price of the laptop
= 126 + 99
= $225
Percentage discount of the laptop
=
99225 x 100%
= 44%
Answer(s): (a) $228; (b) 44%
