Final answer:
To find the original price of the laptop, we need to solve for the original price using the percentage decrease and the given price after the decrease.
Step-by-step explanation:
To find the original price of the laptop, we can use the concept of solving for the original price given a percentage decrease. Let's assume the original price is P. The price after a 10% decrease is $360. We can set up an equation:
P - 0.10P = $360
Simplifying the equation, we get:
0.90P = $360
To isolate P, we divide both sides of the equation by 0.90:
P = $360 / 0.90
Thus, the original price of the laptop is $400.
