(EOQ calculations​) A downtown bookstore is trying to determine the optimal order quantity for a popular novel just printed in paperback. The store feels that the book will sell at four times its hardback figures. It​ would, therefore, sell approximately 3 comma 000 copies in the next year at a price of​ $1.50. The store buys the book at a wholesale figure of​ $1. Costs for carrying the book are estimated at ​$0.30 a copy per​ year, and it costs ​$10 to order more books.

a. Determine the EOQ.

b. What would be the total costs for ordering the books​ 1, 4,​ 5, 10, and 15 times a​ year?

c. What questionable assumptions are being made by the EOQ ​model?

The recent collapse of some banks and financial institutions and the merger of others in ghana is proof that the financial system which consists of institutional units and markets that interact, typically in a complex manner, for the purpose of mobilizing funds for investment and providing facilities, including payment systems, for the financing of commercial activity remains unprotected in spite of the the presence of the Regulator and a solid legal system backing it. From the discussion in class and available literature, examine some of the difficulties associated with the financial system and how these challenges have been addressed by the Banks and Specialised Deposit Taking Institutions Act 2016 (Act 930). Are there any novel ways by which some of the challenges may be resolved in your opinion?

1. Lebanon is currently facing both a foreign debt crisis and a banking crisis. What is the difference between the two? Discuss their implications for Lebanon. How can Lebanon recover?

2. Reflect on levels of economic development and crises like those that currently face Lebanon. How does corruption and fiscal mismanagement leave a country vulnerable to economic disaster? What are the implications of this? How is the situation exacerbated by the novel coronavirus pandemic?

3. How does Lebanon’s persistent trade imbalance contribute to its foreign debt crisis? Would a floating exchange rate help to alleviate the situation? Explain the relationship between exchange rates and imports and exports.

I need the output of the code like this in java

First we create a new building
and display the result:

This building has no apartments.

Press enter to continue.........................

Now we add some apartments to the building
and display the result:

This building has the following apartments:

Unit 1 3 Bedroom
Rent $450 per month
Currently unavailable

Unit 2 2 Bedroom
Rent $400 per month
Currently available

Unit 3 4 Bedroom
Rent $1000 per month
Currently unavailable

Unit 4 1 Bedroom
Rent $500 per month
Currently unavailable

Unit 5 5 Bedroom
Rent $10000 per month
Currently available

Press enter to continue.........................

Now we try to add another apartment to the building
Cannot add another apartment the building is full.

Now we create a new building and add some apartments
then we collect the rent from all the occupied apartments
The total rent collected was: $2500

Finally we use the getUnits method to get a copy of the 3rd unit
from the building and change its rent to $10then we display
the building again to show that the apartment has not changed.

This building has the following apartments:

Unit 1 3 Bedroom
Rent $450 per month
Currently unavailable

Unit 2 2 Bedroom
Rent $400 per month
Currently available

Unit 3 4 Bedroom
Rent $1000 per month

Better Fitness, Inc. (BFI), manufactures exercise equipment at its plant in Freeport, Long Island. It recently designed two universal weight machines for the home exercise market. Both machines use BFI-patented technology that provides the user with an extremely wide range of motion capability for each type of exercise performed. Until now, such capabilities have been available only on expensive weight machines used primarily by physical therapists. At a recent trade show, demonstrations of the machines resulted in significant dealer interest. In fact, the number of orders that BFI received at the trade show far exceeded its manufacturing capabilities for the current production period. As a result, management decided to begin production of the two machines. The two machines, which BFI named the BodyPlus 100 and the BodyPlus 200, require different amounts of resources to produce.

The BodyPlus 100 consists of a frame unit, a press station, and a pec-dec station. Each frame produced uses 4 hours of machining and welding time and 2 hours of painting and finishing time. Each press station requires 2 hours of machining and welding time and 1 hour of painting and finishing time, and each pec-dec station uses 2 hours of machining and welding time and 2 hours of painting and finishing time. In addition, 2 hours are spent assembling, testing, and packaging each BodyPlus 100.

The BodyPlus 200 consists of a frame unit, a press station, a pec-dec station, and a leg- press station. Each frame produced uses 5 hours of machining and welding time and 4 hours of painting and finishing time. Each press station requires 3 hours of machining and welding time and 2 hours of painting and finishing time, each pec-dec station uses 2 hours of machining and welding time and 2 hours of painting and finishing time, and each leg-press station requires 2 hours of machining and welding time and 2 hours of painting and finishing time. In addition, 2 hours are spent assembling, testing, and packaging each BodyPlus 200.

For the next production period, management estimates that 500 hours of machining and welding time; 350 hours of painting and finishing time; and 120 hours of assembly, testing, and packaging time will be available.

The net retail price of the BodyPlus 100 and the BodyPlus 200 are $350 and $445, respectively. Although some flexibility may be available to BFI because of the unique capabilities of the new machines. Authorized BFI dealers can purchase machines for 70% of the suggested retail price. BFI’s president believes that the unique capabilities of the BodyPlus 200 can help position BFI as one of the leaders in high-end exercise equipment. Consequently, she states that the number of units of the BodyPlus 200 produced must be at least 35% of the total production of BodyPlus 100.

Analyze the production problem at Better Fitness, Inc., and prepare a report for BFI’s president presenting your findings and recommendations. The report should include the following items:

The recommended number of BodyPlus 100 and BodyPlus 200 machines (In other words, find the optimal level of production for BodyPlus 100 and BodyPlus 200 using linear programming model).

Objective function: Total profit

BodyPlus 200 requirement constraint

Non-negativity constraint

Time Constraint:

Machining & Welding

Painting & Finishing

Assembly, Test, and Packaging

The effect on profits of the requirement that the number of units of the BodyPlus 200 produced must be at least 25% of the total production of BodyPlus 100. where efforts should be expended in order to increase contribution to profits
