Canvas Problem 2. An electrical engine company has a production capacity of 120 engines per month, and sales are observed to be 100 engines per month without randomness. An engine costs the company $75 to manufacture, while the setup cost of a production run is $950. Holding costs are figured at 28% per year. Answer the following questions: 2.1) (5 points) Write down the model name and list all the parameters of the problem and their numerical values (convert to yearly rates as necessary). 2.2) (5 points) Write down the formula for the optimal number of engines to produce in a production run, and compute it numerically. 2.3) (5 points) Write down the formulas for the time between production runs (cycle length) and its uptime and downtime components, and compute each of them numerically. 2.4) (5 points) When the inventory is at its maximal level in a cycle, what is the amount of dollars tied up in inventory at that point (include all formulas)
