Patient and effective UH grad for High school Math tutoring

Hy Maren,

4000 - 4d = 200

4d = 3800

d = 950

so the value goes down by $950 an year

V = 4000 - 950t

the graph would be straight line with a negative gradient .

the slope represents the amount by which it depreciates each year.

intercept when t = 0 is the initial value or original value of the computer.

Finally when t = 3

V = 4000 - 950(3)

= 4000 - 2850

= 1,150

The tv is worth 1,150 dollars after 3 years .

hope this helped
