Value of Computer Software
The value V, in dollars, of a shopkeeper's inventory is software program is given by V=50t + 300, where t is the number of years since the shopkeeper first bought the program. SHOW YOUR WORK for a and c.
a) Find the value of the software after 0 years, 4 years, and 6 years.
b) Use graph paper to graph the equation and then use the graph to estimate the value of the software after 5 years.
c) After how many years is the value of the software $150?

V = 50t + 300.
a. V = 50*0 + 300 = $300.
V = 50*4 + 300 = $100.
V =
b. The following points maybe used for graphing:
(t,V) = (0,300), (2,200), (4,100),
(6,0).
c. 50t + 300 = 150 Solve for t.
