3. A van conversion company has fixed capital and labor expenses of $1 .2 million per year, and variable expenses averaging $8,000 per van conversion. Recent experience suggests the following annual demand for their product: Q = 4000 - .25P Where Q is the number of van conversions (output) and P is price. Calculate the prot-maximizing output, price, and prots. Assuming a parts shortage limits their output to 600 conversions per year, use the Lagrangian multiplier method to calculate the profit-maximizing output, price, and prots. c. Calculate and interpret the size of the Lagrangian multiplier. 53"?\
