Answer:
c. 2.50 years
Explanation:
In the payback, we analyze in how many years the invested amount is recovered. The computation is shown below:
In year 0 = $500
In year 1 = $150
In year 2 = $200
In year 3 = $300
If we sum the first 2 year cash inflows than it would be $350
Now we deduct the $350 from the $500 , so the amount would be $150 as if we added the fourth year cash inflow so the total amount exceed to the initial investment. So, we deduct it
And, the next year cash inflow is $300
So, the payback period equal to
= 2 years + ($150 ÷ $300)
= 2.50 years
In 2.50 yeas, the invested amount is recovered.
The government may either sell goods or render services like train, city bus, electricity, transport, posts and telegraphs, water supply, etc. The government also earns revenue from the production of commodities like steel, oil, life-saving drugs, etc.
Managers, this is symbolic of how business is run in U.S. culture.
Answer:
Suppose the cost per hour incurred in operating a cruise ship is 3a + b 
dollars per hour, where a and b are positive constants and v is the ship's speed in miles per hour. At what speed (in miles per hour) should the ship be operated between two ports, at a distance D miles apart, to minimize the cost? (Hint: Minimize the cost, not the cost per hour.)
<em>The speed at which the ship would maximize cost is </em>![\sqrt[3]{\frac{3a}{2b} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B3a%7D%7B2b%7D%20%7D)
Explanation:
The problem can be solved using differentiation to get the minimum value of the speed to travel between the two ports. Step by step calculation is contained in the attached images;
