aleksley [76]

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>

<h3>What is Algebra?</h3>

= (-5)^{4} *y^{4}

= (-5y)^{4}

Hence, (-5)*(-5)*(-5)*(-5)*y*y*y*y = (-5y)^{4}
