- Why should a firm shut down immediately when it can no longer cover their variable.arrow_forwardOn the occasion of summer vacation, a student plans to open a milk tea shop. Before deciding to open a store, she wants to find out how profits fluctuate with fluctuations in selling prices and costs per unit of product. The selling price per cup of milk tea can range from VND 20,000.00 to VND 30,000.00 (the level of change is VND 1,000.00 each time) and the cost to make a cup of milk tea can range from VND 13,000.00 to VND 17,000.00 (the level of change is VND 500 each time). Knowing that the initial fixed cost is VND 24,000,000.00 and the number of cups of milk tea sold (Demand) depends on the selling price according to the formula: Demand = 24000 - 0.5 * Unit Price Use the two-dimensional sensitivity analysis to answer the following questions: a) What is the profit if the selling price is 23,000.00 VND and the cost per unit is 15,000.00 VND? b) How will profit change with each increase in cost of a product unit by VND 500.00 with a constant selling price of VND 25,000.00? c) What is…arrow_forwarddefine total fixed costsarrow_forward

- I need help with this problem for business calculus. The revenue given is R(x)=275(0.974)^2x+1 I have to find the marginal revenue when 150 computers are sold and interpret the answer in a sentence. I know that I have to find the Marginal revenue function and I think it's -14.48918*0.974^2x+1 but I'm not 100% sure. I also need some clarification if I need to plug 150 into x to get the marginal revenue for 150 computers sold. Please help, thank you!arrow_forward1200 100.0 20.0 F20 100 -100 A company produces school buses. The graphs of the Cost function (red) and the Revenue function (blue) are given on the figure. (You may click on the figure to see a bigger version.) The horizontal axes represents quantity in number of units. Cost and Revenue are measured in thousands of dollars. Answer the following questions. 1. What are the fixed costs? Answer: thousand dollars. 2. Suppose the current level of production is 19 buses. Should the company produce 20 th bus? Answer "yes" or "no" 3. Between 0 and 100, approximately what level of production maximizes the profit? (Or minimizes the losses if the company doesn't make any profit).
