The first question: - Assume that the fixed costs of one of the productive factories are equal to 100,000 riyals and that the variable cost of one unit is 5 riyals and the selling price of one unit is 10 riyals. The following is required to calculate: 1- The amount and amount of the break-even, using the contribution limit method. (With the law mentioned first) 2 - Break-even point with a profit of 50,000 riyals. (With the law mentioned first) The second question: - You have the following information about the cash flows of an investment project. Note that the cost of the investment project = 5000000 calculate the following the years The cost of the investment project 1 2 3 4 5 6 Project A. 2250 400 450 500 550 600 650 project B. 2250 525 525 525 525 525 525 1- Calculate the payback period, and choose the appropriate project 2- Calculate the net present value, noting that the remaining value of the three projects is non-existent. And that the interest rate on capital K = 10%, then I choose the appropriate project
