Which of the following is necessary to calculate the variable cost of production for the company to develop a profit model?

Use a modern software tool to perform statistical calculations. Use the table below to answer the following question(s). Fiberia Accessories, a clothing retailer, is planning to introduce a new line of sweaters as part of the winter collection for $65 with an inventory of 1500. The main selling season is 60 days between November and December. The store then sells the remaining units in a clearance sale at 65 percent discount. Out of the 60 main retail days, Fiberia sells the sweaters at full retail price for only 45 days, while giving a discount of 25 percent for the remaining 15 days. The demand functions a, and b are given as 79.5 and 1.1 respectively.

Use the table below to answer the following question(s). In the spreadsheet below, there is data on the price, cost, demand, and quantity produced for an item. There are also different "what if" values that can help a manager to calculate costs and revenue with variability in demand. $\begin{array}{|l|l|l|l|}\hline & \text { A } & \text { B } & \text { C } \\\hline 1 & \text { Profit Model } & & \\\hline 2 & & & \\\hline 3 & \text { Data } && \begin{array}{l}\text { What-If } \text { Demand } \\\text { Values }\end{array} \\\hline 4 & & & 20,000 \\\hline 5 & \text { Unit Price (\$) } & 50 & 40,000 \\\hline 6 & \text { Unit Cost (\$) } & 25 & 55,000 \\\hline 7 & \text { Fixed Cost (\$) } & 550,000 & 60,000 \\\hline 8 & \text { Demand } & 60,000 & 65,000 \\\hline 9 & \text { Quantity Produced } & 55,000 & \\\hline 10 & & & \\\hline\end{array}$ -From the "what if" values, calculate the net profit when the demand is 65,000.

Use the table below to answer the following question(s). Sheila joined Simsin Tradings at the age of 36 with a starting salary of $75,000. She expects a salary increase of 5 percent every year. Her retirement plan requires her to pay 9 percent of her salary, while the company matches it at 32 percent. She expects an annual return of 7 percent on her retirement portfolio. Using a predictive model for Sheila's first five years, calculate the following, assuming that the salary increases at the same rate every year, and the return of interest does not change. Retirement Plan Model for Sheila Data Retirement Contribution (percent of salary) 9 percent Employer Match 32 percent Annual Salary Increase 5 percent Annual Return on Investment 7 percent -What's the total retirement balance when Sheila has reached the age of 40 while working with Simsin?

Use the table below to answer the following question(s). Below is a room overbooking model spreadsheet for the Metza, a hotel chain. The hotel has 425 rooms priced at $180 per day each, and is usually fully booked. Reservations can be cancelled any time before 5:00 p.m. with no penalty. The hotel estimates an average overbooking cost of $150. Customer demand is set at 400 with an average cancellation of 20.
