I have done it and wanna check if I had done it wrong. Please give me the result to compare

d. If marginal cost were to increase by 30 at each level of output at what point would prots be maximized? (1 mark) e. Given the original level of marginal cost, at what level of output would the rm maximize prots if marginal revenue were to increase by 34 at each level of output? (1 mark) (Total 7 marks) SECTION D: [38 Marks] Chapter 7: Costs and Supply 11. A rm making toffees has a choice between three production techniques, each using different combinations of labour input and capital input, as shown in the table below. Suppose labour costs 200 per unit / week and capital input costs 400 per unit/ week. Technique A Technique B Technique C L K 4 6 2 8 10 3 4 12 14 4 5 16 19 5 6 20 25 6 7 24 32 7 I 120 8 45 38 29 40 a. For each level of output; state which production technique should be adopted by the rm. 1). Calculate total cost for each level of output. c. Suppose the price of labour input increases to 300 per unit! week, but the price of capital remains constant. In what way would you expect the rm's choice of technique to be affected by this change in relative prices? (I. With the new labour cost, state which production technique should be adopted for each output level and calculate total cost. (Each point carries 2 marks. Total 8 marks) 12.
