Question

$4000. After 4 years the value of the computer is expected to be$200. For accounting purposes the business uses linear depreciation to assess the value of the computer at a
given time. This means that if V is the value of the computer at time t, then a linear equation is used to relate V
and t.
(a) Find a linear equation that relates V and t.
(b) Sketch a graph of this linear equation.
(c) What do the slope and V-intercept of the graph
represent?
(d) Find the depreciated value of the computer 3 years from
the date of purchase.
