Answer:
The incremental benefit cost ratio is less than 1 therefore we must select site 1.
Explanation:
The incremental BCR can be determined using the following formula

8% , 10)
⇒ 
⇒
8%, 20)
⇒ 
⇒
= $203,704.42
Incremental initial investment = 203,704.42 - 149,029.49
= $ 54,674.93
Incremental benefits = 580,000 - 520,000 = 60,000
Incremental O&M = 75,000 - 80,000 = - $ 5000
Incremental Disbenefits = 140,000 - 90,000 =$ 50,000

All solving using the present worth method also incremental benefit cost ratio comes out to be 0.2743.
The incremental benefit cost ratio is less than 1 therefore we must select site 1.
Answer:
Number of car washed is 92
So option (a) is correct answer
Explanation:
It is given that 4 workers can wash 80 cars per day
Means initially 80 cars are washed per day
And it is given that rate of car wash is $5 per car
Now price of workers is $60 per day
As per car wash is $5
So number of extra car washed 
So total number of car washed = 80 + 12 = 92 cars per day
So option (a) is correct answer
Answer:
C. Organize staff
Explanation:
C. Organize staff is the answer.
Answer:
preferred stockholders received $15,000 during the first 3 years
- $2,000 in the first year
- $6,000 in the second year
- $7,000 in the third year
common shareholders received $25,000 in dividends during the third year.
Explanation:
preferred stock = 1,000 shares x $100 par value x 5% = $5,000
common stock = 10,000 shares at $10 par value
dividends declared and paid during the first 3 years:
year dividends
1 $2,000
2 $6,000
3 $32,000
preferred stockholders should have received $5,000 per year x 3 years = $15,000. Preferred stockholders must be paid first, and their payment is fixed. If the dividends are not enough to pay the total amount, the remaining amount should be paid next year.
- $2,000 in the first year
- $6,000 in the second year
- $7,000 in the third year
common shareholders received $32,000 - $7,000 = $25,000 in dividends during the third year.
