The value V, in dollars, of a shopkeeper’s inventory software program is given by V=-50t+300,
where t is the number of years since the shopkeeper first bought the program. Find the value of the software after 4 years.
Substitute 4 for t and solve.
To find the value of the software after 4 years, we need to substitute the value of t = 4 into the given equation V = -50t + 300.
So, let's plug in t = 4 into the equation:
V = -50(4) + 300
Now, perform the calculation:
V = -200 + 300
V = 100
Therefore, the value of the software after 4 years is $100.
