The problem below involves three variables. Solve it with the simplex method, Excel, or some other technology.
Patio Iron makes wrought iron outdoor dining tables, chairs, and stools. Each table uses 8 feet of a standard width wrought iron, 2 hours of labor for cutting and assembly, and 2 hours of labor for detail and finishing work. Each chair uses 6 feet of the wrought iron, 2 hours of cutting and assembly labor, and 1.5 hours of detail and finishing labor. Each stool uses 1 foot of the wrought iron, 1.5 hours for cutting and assembly, and 0.5 hour for detail and finishing work, and the daily demand for stools is at most 16. Each day Patio Iron has available at most 164 feet of wrought iron, 72 hours for cutting and assembly, and 50 hours for detail and finishing. The profits are $60 for each dining table, $48 for each chair, and $36 for each stool.
Suppose Patio Iron wants to maximize its profits each day by making dining tables, chairs, and stools.

The following model shows a calculation of the total cost to produce a million copies of the novel, based on an analysis of setup and storage costs c(n) = 0.0008n² - 74n+ 2,000,000 dollars, where n is the print run size (the number of books printed in each run). (a) What would be the effect on cost if the run size was increased from 20,000 to 30,000? A run of size 20,000 would cost $ and a run of 30,000 would cost $ dollars. $30,000 per month would result in a savings of Thus, increasing the run size from $20,000 to (b) Would increasing the run size in further steps of 10,000 result in the same changes in the total cost?

- Use the Simplex Method to solve the following problem. Show all work. 2. A contractor builds three types of houses; the Aries, the Belfair and the Wexford. Each house requires one lot and the following table gives the number of labor-hours and the amount of capital needed for each type of house, as well as the profit on the sale of each house. There are 12 lots, 47,500 labor-hours and $3,413,000 available for the contractor's use. Belfair 3,700 $279,600 $25,000 Wexford 5,000 Aries 3,000 $205,000 $20,000 Labor-hours Capital Profit $350,000 $30,000 a. Building how many of each type of house will maximize her profit b. What is the maximum possible profit?arrow_forwardSolve the following using Simplex Method. 1. A factory makes three types of chairs, A, B, and C. The factory makes a profit ci P200 on chair A, P300 on chair B, and P400 on chair C. Chair A requires 30 man-hours, chair B requires 20, and chair C requires 10. Chair A needs 2m2 of wood, chair needs 5m2, and chair C needs 3m2. Given 100 man-hours and 15m2 of wood per week, how many chairs of each type should be made each week to maximize profit? 2. Maximize Z = 8x +6 x Subject to: 10x,+ X2s 12 2xi+ 5 x2s 16 X120 INHarrow_forwardSet up the initial simplex tableau that could be used to solve the following problem by the simplex method. The Fancy Fashions, an independent, local boutique, has $9000 available each month for advertising. Newspaper ads cost $500 each, and no more than 30 can run per month. Internet banner ads cost $25 each, and no more than 70 can run per month. TV ads cost $1000 each, with a maximum of 10 available each month. Approximately 5000 women will see each newspaper ad, 3000 will see each Internet banner, and 10,000 will see each TV ad. How much of each type of advertising should be used if the store wants to maximize its ad exposure? Let x₁ = the number of newspaper ads. Let x₂ = the number of Internet banner ads. Let x3 = the number of TV ads. Complete the initial simplex tableau below. X1 x₂ 500 1 0 х3 $1 82 25 2000 1 1 0 1 0 0 0 1 0 0 0 1 0 0 $3 $4 0 0 0 0 0 0 0 1 0 0 1 1 0 0 NO 0 8000arrow_forward
