FasterTrucks Ltd is a transport company. The
enterprise needs to decide if a new delivery
vehicle will be purchased. Two models are
currently considered. You are required to
indicate which one of the two models should
be purchased. You decide to apply the method
of EQUIVALENT UNIFORM ANNUAL COST.
Since the economic lifetimes of the two models
differ, you will have to apply the replacement
chain approach. Assume that the company’s
cost of capital amounts to 10% per year.
The following information is provided to you:

The purchase price of the vehicle amounts to
R150 000 now. Furthermore, the vehicle needs
to be adjusted at a total cost of R30 000 now.
The purchase price and the cost of adjusting
the vehicle are not expected to change during
the next ten years. The vehicle’s expected
economic lifetime is estimated as three years.

The answer is = R 72 380.66

I know you have to get the present value of the vehicle and then calculate the annual payments but I am not sure how to get this answer?

This was the method used to get the answer:

PV= -180 000 - 180 000/(1.10)^3 = 315 236.66

Then,

PV= 315 236.66
N=6
i=10%

therefore PMT= 72 380.66

Your PV calculation is correct.
Payment formula:
A = amount (72380.66)
n = number of payments (6)
i = interest factor (.10)
P = Ai / [1 - 1/(1 + i)^n] : that's work out to 72380.66

However, no idea where the "6 years" comes in.
Problem only mentions 3 years.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
I'm interested to know whether the equation $$1 = 2 - \frac{1}{2 - \frac{1}{2 - \cdots}}$$ is true or not. It can be shown easily that if the continued fraction converges, it cannot converge to anything else than 1. It seems that if the continued fraction converges, the convergence is very slow. The apparent slowness of the convergence makes it difficult to estimate the presence of true convergence numerically. At the moment I don't know whether this converges or not.
