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.
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.
