Answer:
<u>The original price of the laptop was US$ 875</u>
Step-by-step explanation:
1. Let's review all the information given for solving this question:
Sale price of the laptop = US$ 525
Discount from the original price = 40%
2. Let's find the original price of the laptop
Original price of the laptop = x
Sale price of the laptop = US$ 525
Sale price of the laptop = x - 40%x
525 = x - 0.4x
525 = x - 4x/10 (0.4 = 4/10)
5,250 = 10x -4x (Multiplying by 10 at both sides)
5,250 = 6x
5,250/6 = 6x/6 (Dividing by 6 at both sides)
875 = 6
<u>The original price of the laptop was US$ 875</u>
