Explanation of Solution

The total cost of catching 30 tons of fish by ‘ER’ can be calculated as follows:

Total cost=((First five tons×Cost per tonfor 5 tons)+(Total quantity required5 tons)×Cost per tonAbove 5 tons)=(5×1,000)+(30tons5tons)×2,500=5,000+62,500=67,500

To catch 30 tons, the cost for ‘ER’ is $6,000.

The total cost of catching 30 ton fish by ‘KY’ can be calculated as follows:

Total cost=((First 15 tons×Cost per tonAbove 15 tons)+(Total quantity required15 tons)×Cost per tonAbove 15 tons)=(15×3,000)+(30tons15tons)×1,400=45,000+21,000=66,000

To catch 30 tons, the cost for ‘KY’ is $66,000.

 Since the total cost of fishing for ‘KY’ is less than the other person, ‘KY’ should catch the entire fist.

The average cost can be calculated as follows:

Average cost=Total costTotal quantity=66,00030=2,200

The average cost is $2,200 per ton.

Explanation of Solution

The first five ton cost of fishing for ‘ER’ is less than the ‘KY’. The additional ton cost for ‘ER’ is greater than the additional cost of ‘KY’. Thus, first 5 tons should be caught by ‘ER’ and the remaining fish should be caught by ‘KY’. The total cost for this combination can be calculated as follows:

Total cost=((First 5 ton ER×Cost per ton ERFor 5 tons)+(First 15 ton KY×Cost per ton KYAbove 15 tons)+(Total quantity required KY15 tons)×Cost per ton KYAbove 15 tons)=(5×1,000)(15×3,000)+(25tons15tons)×1,400=5,000+45,000+14,000=64,000

The total cost is $64,000.

The average cost can be calculated as follows.

Average cost=Total costTotal quantity=64,00030=2,133.33

The average cost is $2,133.33 per ton.

Sub Part (c):

To determine

The ER's profit.

Explanation of Solution

ER’s total profit can be calculated as follows.

Total profit=Quantity×Price((First five tons×Cost per tonfor 5 tons)+(Total quantity required5 tons)×Cost per tonAbove 5 tons)=30×3,000((5×1,000)+(30tons5tons)×2,500)=90,000(5,000+62,500)=22,500

ER’s total profit is $22,500. ER’s total profit after selling 25 tons can be calculated as follows.

Total profit=(Quantity5 tons×(PriceCostFor 5 ton))+(Quantity sold×Selling priceITQ)=(5×(3,0001,000))+(25×550)=10,000+13,750=23,750

ER’s total profit after selling the ITQ is $23,750.

Sub part (d):

To determine

Who would be willing to offer $500 for additional 25 tons.

Sub part (d):

Expert Solution
Check Mark

Explanation of Solution

The person ER can earn $500 (3,0002,500) per unit for additional 25 tons. Thus, the person KY would ready to offer $500 for the additional 25 tons.

1. Imagine a society that produces military goods and consumer goods, which we'll call "guns" and "butter." a. Draw a production possibilities frontier for guns and butter. Using the concept of opportunity cost, explain why it most likely has a bowed-out shape. b. Show a point that is impossible for the economy to achieve. Show a point that is feasible but inefficient. c. Imagine that the society has two political parties, called the Hawks (who want a strong military) and the Doves (who want a smaller military). Show a point on your production possibilities frontier that the Hawks might choose and a point the Doves might choose. d. Imagine that an aggressive neighboring country reduces the size of its military. As a result, both the Hawks and the Doves reduce their desired production of guns by the same amount. Which party would get the bigger "peace dividend," measured by the increase in butter production? Explain.
A health study tracked a group of persons for five years. At the beginning of the study, 20%were classified as heavy smokers, 30% as light smokers, and 50% as nonsmokers. Resultsof the study showed that light smokers were twice as likely as nonsmokers to die duringthe five-year study, but only half as likely as heavy smokers.A randomly selected participant from the study died during the five-year period.
