This land was purchased by the Gulf Shrimp Processing Division. If this current site is used for the catfish project, then Gulf Shrimp would need to find a different site. The best option would be for the Gulf Shrimp Processing Division to take advantage of buying an option for $100,000 to buy the site in five years for $1,300,000 compared to having no option and the price being $1,500,000. Table 1 shows the present value of these options. By purchasing the land with the $100,000 option, the present value is $907,198 with a 10% interest rate, discounted five years.

Coca-Cola’s Production Orange Juice is considered as an unstructured problem, due to the fact that its production is even more complicated than bottling soda, the production of the Orange juice requires a complicated process that involves mathematical algorithms, modules, and business applications. Decisions rely and depends on the nature of the problem and obtained solutions as a result, the solution that has been taken for this obstacle is to resolve this issue from the roots. That is the main reason of the exclusion/classification of problems is divided into structured and unstructured problems in business sectors. Question 2

Measurements, Calculations, and Significant Figures Measurements, calculations, and significant figures are vital mathematical terms used to understand the basic concepts of physics. Knowing how to properly make measurements and apply the necessary calculations to obtain accurate answers will surely prove beneficial in physics, but having that knowledge will also help you throughout your entire life. Therefore, it is important to understand the processes and numbers involved when using measurements, calculations, and significant figures. Measurements are used to identify the specific characteristics of an object, such as length, size, and amount. One must use the proper measuring device, depending on the conditions of the experiment and
