Answer: $8,000
Explanation:
If you're satisfied, the cost of software C is:
= 5,000 + 0
= $5,000
If you are not satisfied, the cost is:
= 5,000 + 20,000
= $25,000
You can then use the probabilities to calculate the expected total cost:
= (Probability of satisfied * Cost if satisfied) + (Probability of unsatisfied * Cost if unsatisfied)
= (80% * 5,000) + (20% * 20,000)
= $8,000
