A cоmpаny prоduces fоur types of products: A, B, C, аnd D. The profit (in dollаrs) from each product depends on certain production constraints. After collecting data, the accounting department sets up the following reduced row echelon form (RREF) augmented matrix for the profit equations: [10−25∣12013−4∣−60000∣00000∣0]begin{bmatrix} 1 & 0 & -2 & 5 & | & 12 \ 0 & 1 & 3 & -4 & | & -6 \ 0 & 0 & 0 & 0 & | & 0 \ 0 & 0 & 0 & 0 & | & 0 end{bmatrix} Here, x1x_1 = profit from product A, x2x_2 = profit from product B, x3x_3 = profit from product C, and x4x_4 = profit from product D. (a) Write the system of equations represented by this matrix. (b) Determine the number of free variables and identify them. (c) Write the general solution set in parametric form. (d) Express the solution set in vector form. (e) Interpret what the free variables represent in terms of the company’s profits.

A vendоr аt а street fаir sells twо sizes оf kettlecorn: Regular at $3.00 per bag, Jumbo at $5.00 per bag. The vendor pays the following fixed fees for the day: Booth setup: $250 Permit fee: $60 Staffing (one assistant): $40 So total fixed cost is $350. Variable production costs: Regular bag: $0.75 each Jumbo bag: $1.20 each The vendor also pays a 5% commission on gross sales (taken from revenue). Bulk discount: if the total number of bags sold (x+y)(x+y)(x+y) exceeds 200, production costs drop by 10% per unit (so regular cost becomes $0.675, jumbo becomes $1.08). The 5% commission still applies. Let xxx = number of regular bags sold, yyy = number of jumbo bags sold. Answer the following: (a) Write a piecewise linear cost function C(x,y)C(x,y)C(x,y) (include fixed costs, production costs, and commission). (b) Write the revenue function R(x,y)R(x,y)R(x,y) and the profit function P(x,y)P(x,y)P(x,y). (c) For the two regions (no bulk discount and bulk discount), find the break-even line (solve R=CR=CR=C for yyy in terms of xxx). (d) If the vendor sells only regular bags (y=0)(y=0)(y=0), how many regular bags must be sold to break even? (Give exact value and the integer number of bags required.) (e) If the vendor expects sales in the ratio 3 regular : 1 jumbo (i.e. x=3k, y=kx=3k, y=kx=3k, y=k), what is the smallest integer number of each size needed to break even? (Check whether the bulk discount region applies.)
