a.

b.  $900

c. $150

Step-by-step explanation:

Given:  The value of laptop decreases $150 each year .It means it is a linear function.

If after 2 years the laptop is worth $600.

Then the original value of laptop=

Now, Let V be the value of the laptop x years after it is purchased.

Then will be the required equation .

To find the value of the laptop 5 years after it is purchased, put x=5 in the equation, we get

Thus, the value of laptop after 5 years = $150
