The method to be used for 2.1 and 2.2 is Least Square Regression. Please provide complete solution (step-by-step) with thorough analysis and explanation. Thank you!

PROBLEMS 2.1 The following information summarized total production costs and number of units of product produced by Rosalyn Company over the last 6 months: Units Month Produced Total Cost 30,000 P24,000 42,000 30,000 40,000 32,000 QUIAWN 34,000 27,000 32,000 23,000 31,000 23,000 1. Determine the cost formula 2. What would be the total cost if the company plans to produce 35,000 units? 3. What would be the total cost if the company plans to produce 25,000 units? 2.2 An organization has the following total costs at two activity levels P150,000 @ 16,000 units; P200,000 @ 24,000 units Variable costs per unit is constant in this range of activity and there is a step down of P20,000 in the total fixed costs when activity is below 18,000 units. 1. What is the total cost at an activity level of 17,000 units? 2. What is the total cost at an activity level of 25,000 units? 2.3 RR Company uses the high-low method to analyze cost behavior. The company observed that at 2,000 machine hours of activity, total maintenance costs averaged P40.00 per hour. When activity jumped to 6,000 machine hours, the average cost per machine hour totaled P35. If the number of machine hours would exceed 5,000, fixed cost would increase by P20,000. On the other hand, if it will be below 1,000 machine hours, fixed cost would decrease by P10,000. But, regardless of the number of machine hours, variable cost per unit remains constant. 1. If RR plans to incur 4,500 machine hours, the total cost would be 2. If RR plans to incur 5,300 machine hours, the total cost would be CS Scanned with CamScanner
