Non-linear programming (NLP):
Non-linear programming (NLP) is used in complex optimization problems where the objectives or constraints or sometimes both are non-linear functions of the decision variables. A model can be termed as non-linear for more than one reason.

Your answer is partially correct.
An independent contractor for a transportation company needs to determine whether she should upgrade the vehicle she currently
owns or trade her vehicle in to lease a new vehicle. If she keeps her vehicle, she will need to invest in immediate upgrades that cost
$5,200 and it will cost $1,300 per year to operate at the end of year that follows. She will keep the vehicle for 5 years; at the end of this
period, the upgraded vehicle will have a salvage value of $3,800. Alternatively, she could trade in her vehicle to lease a new vehicle. She
estimates that her current vehicle has a trade-in value of $9,800 and that there will be $4,100 due at lease signing. She further
estimates that it will cost $2,900 per year to lease and operate the vehicle. The independent contractor's MARR is 11%. Compute the
EUAC of both the upgrade and lease alternatives using the insider perspective.

A young computer engineer has $12,000 to invest and three different investment options (funds) to choose from. Type 1 guaranteed investment funds offer an expected rate of return of 7%, Type 2 mixed funds (part is guaranteed capital) have an expected rate of return of 8%, while an investment on the Stock Exchange involves an expected rate of return of 12%, but without guaranteed investment capital. Computer engineer has decided not to invest more than $2,000 on the Stock Exchange in order to minimize the risk. Moreover for tax reasons, she needs to invest at least three times more in guaranteed investment funds than in mixed funds.
Assume that at the end of the year the returns are those expected; she is trying to determine the optimum investment amounts.
(a) Express this problem as a linear programming model with two decision variables.(b) Solve the problem with the graphical solution procedure and define the optimum solution.
You are the Economic Consultant for Zuku Farms Ghana Limited. Zuku produces cowpea in a community where producers are able to switch back and forth between cowpea and groundnut depending on market conditions. Consequently, you were tasked by the management of Zuku and you estimated the demand function for cowpea as follows:
where is the quantity of cowpea demanded in bags per month, is the average price of cowpea in Ghana Cedis, is the average price of groundnut in Ghana Cedis, and Y is the income of consumers. Assuming is initially GH¢31.00 per bag, Y is GH¢1001.50
Required:
Find the resulting demand function for cowpea and determine the number of bags Zuku can sell at GH¢ 45.00 per bag.
Management is considering increasing price of cowpea by GH¢10.00 per bag. Advise management on this price change using the concept of price elasticity of demand.
Explain why management should be worried about a reduction in the price of groundnut

Due to political unrest coupled with the slow recovery from pandemic, the global price of petrol surged which led to an increase of price per litre of petrol in your country from TK58 to TK88. After the price rise, the employees of the company you work for demanded a pay-raise. Your employer, hence, increased your income from 32954 taka to 42762 taka. The new demand curve at the new income level is P = 139 - 3QD. i. Calculate the income elasticity of demand (YED). ii.

OneRing Company sells memorabilia to residents of Middle-Earth. They are about to invest $6 million in a new ring making plant. Fixed costs of operating the plant are $1 million a year. The ring costs $60/unit to manufacture (variable cost) and will be sold for $200/unit. The plant will last for 5 years, and will be depreciated over 5 years to zero using the straight-line method. The plant will have no salvage value after five years. Net working capital requirements are negligible for this project. Assume there are no taxes in Middle-Earth, and that the appropriate discount rate for the project is ten percent. How many rings per year must OneRing sell in order to break even?arrow_forward
