1. (3 points) Suppose that a firm produces three types of output. The levels of output by this firm are given in the column vector: 15,000 Q = 27,000 13,000 and the unit prices of these outputs are given by the row vector P = [7 10 4]. Use the inner product to determine total revenue (TR) for this firm, if the firm can successfully sell its products at the given unit prices. Show your work. The final answer must be a scalar. 2. (4 points) Apply the Laplace Expansion Method to the following 4x4 determinant, along any row or column of your choice. Reduce the 4x4 determinant to a series of 3x3 determinants with the Laplace Expansion and no need to go any further, nor to calculate the final scalar answer for the 4x4 determinant.
