A piece of equipment was purchased by a company for $15,000 and Is assumed to have a salvage value of $5,000 in 5years. If it’s depreciated linearly from $15,000 to $5000
Find a linear equation in the form V = mt + b

Respuesta :

V= -2000t +15000

Step-by-step explanation:

Present the information given as coordinate point where, at purchase time, x=0, value of equipment, y=$15000

This is (0,15000).

After depreciating linearly in 5 years, the salvage value, is $5000

This is (5,5000)

Finding the slope of the graph,

m=Δy/Δx

m=5000-15000/5-0

m= -10000/5 = -2000

y-intercept = 15000

The equation in form of V=mt +b where

V=value of equipment after time t

m=slope of the graph

b=y-intercept

Equation ⇒ V= -2000t +15000
