"Suppose that a company has just purchased a new computer for $2100. The company chooses to depreciate using the straight-line method for 7 years. Write a linear function that expresses the book value of the computer as a function of its age." I don't see how they got "V(x)=-300x+2100" as the answer. Help??

s0 7x=2100, solving for x, x=300

this means that every year the computer value will drop $300 dollars, at the end of x years it would drop 300x dollars

since the price is dropping, this part of the equation gets a negative

the equation becomes v=-300x+2100
