I have added the solution, I need guiadance of how to go about the problem from start.

Please show all steps for iterations and solutions for me to understand (and solve more like this type) the solution is Given for the problem FYI.

Identify the etwork approach and solve the following problem " I have just purchaseda new car for $12,000. The cost of maintaining a car during a year depends on the age of the car at the beginning of the year, as given in Table 1. To avoid the high maintenance costs associated with an older car, I may trade in my car and purchase a new car. The price I receive on a trade in depeds onthe age of the car at the time of the trade-n (see Table 2). To simplify the computations, we assume that at any given time, it costs S12,000 to purchase a new car. My goal is to minimize the net cost incurred during the next five years. Table I Car Maintenance problems Age of car 0 Annual Maintenance $2000 $4000 $5000 S9000 $12000 cost (cumulative) Table 2 Car Trade-in Price Age of car Trade-In Price $7000 S6000 $2000 S1000 S0
