A project requires $180,000 as first cost (investment). Three scenarios were identified, and the following table presents the values of the project key parameters associated with these scenarios:

Key project parameters	Scenario 1	Scenario 2	Scenario 3
Net annual savings, $$	20,000	25,000	30,000
Depreciation rate, %	6	4	2
Service life, years	5	7	10

Probabilities of the first two scenarios are 0.3 and 0.5 respectively. Calculate the expected value of the project's annual worth if market interest rate is 5.5%
