Question

how would i solve question 10d for finding the value of an asset after n units of use?

Answer 1

V_n=5000=29000-.25n

So solve for n

Hint: you already know the value of V_n, so you can ignore that third of the equation

Answer 2

i’m trying to solve 10D. I’ve tried just about everything, and i know how to solve the ones before it, but just not this.

Answer 3

If you get stuck, one way to get un-stuck is to simply plug in #s and see what happens.  After a few #s, you should get a feel for how the equation behaves.

n=0; V = 29,000

n=1000; V = 29,000 - 1000\*0.25 = 29,000 - 250 = 28,750

n=10,000; V = 29,000 - 2500 = 26,500

n=100,000; V = 29,000 - 25,000 = 4,000 \[I went too far <passed my desired value of 5,000; at least you know the answer is n < 100,000\]

This isn't the mathematical way of solving something but it's a way to get you thinking along a different path.
