Answer:

Asking 50 people entering the cafeteria and Asking 120 randomly-selected students.

Step-by-step explanation:

jacob is going shopping he finds a great deal on a laptop foe 40% off the original price if the sale price is $525 what is the o
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>
