Sir i am stuck for this question

2. A rm is using 7' units of labor and 100 units of capital to produce 1000 units of goods. At these levels of inputs, the marginal product of labor is 5 and the marginal product of capital is 50. The cost of labor is $15 per unit and the cost of capital is $2 a unit. Is the rm minimizing its costs? If not explain how the rm could save on costs while still producing 1000 units. 3. Firm A and Firm B produce a homogenous good and compete via Bertrand competition. That is, they both post prices consumers see both prices and go to the rm with the lowest price. If the marginal cost of production is 6H for Firm A and ch for Firm B, what will be the equilibrium price if ct,1
