Answer:
Total cost = $42000
Step-by-step explanation:
Alistar’s 6-year investment plan consists of two periods :
Period 1 : From year 1 to year 3
Period 2 : From year 4 to year 6
In the first period, from year 1 to 3,
Alistar make investment on his education.
In the second period, from year 4 to 6,
Amount which he starts earning = $32000
And the annual income of him = $25000
⇒ Alistar receives additional $7000 every year
Now, time taken to recover his investments = 6 years
Hence, Total cost = 7000 × 6
= $42000
