The value of business furniture is assumed to depreciate (decrease) in value linearly. If the value was $56,000 in 2012 and $48,500 in 2015, when will the value be $20,000?
Setup an equation for the value and solve algebraically.

Answer:

In the year of 2026.

Step-by-step explanation:

The value of the business furnite in t years after 2012 is given by an equation in the following format:

[tex]V(t) = V(0) - at[/tex]

In which V(0) is the value in 2012, and a is how much the value decreases a year.

If the value was $56,000 in 2012 and $48,500 in 2015

This means that [tex]V(0) = 56000, V(3) = 48500[/tex]

So

[tex]V(t) = V(0) - at[/tex]

[tex]48500 = 56000 - 3a[/tex]

[tex]3a = 7500[/tex]

[tex]a = \frac{7500}{3}[/tex]

[tex]a = 2500[/tex]

So

[tex]V(t) = 56000 - 2500t[/tex]

When will the value be $20,000?

t years after 2012, in which t is when V(t) = 20000. So

[tex]V(t) = 56000 - 2500t[/tex]

[tex]20000 = 56000 - 2500t[/tex]

[tex]2500t = 36000[/tex]

[tex]t = 14.4[/ttex]

This will happen in 14.4 years after 2012, so in the year of 2026.
