How to work this problem out?

Question

A printing company estimates that an item of equipment purchased today (t=0), for $120000, will depreciate linearly such that in 8 years time, (t=8) it will be worth $56000. Determine a formula for V, the dollar value of the item, after t years.

Answer 1

ZZZ

V(0) = 120000

V(8) = 56000

So V drops by 64000 in 8 years, which is 8000 per year

Answer: V(t) = 120000 - (8000 x t)
