    isolating the variables seems to be the hardest part of this lesson given the rest is really just algebra. thank you

      True! because I only isolated the number of scientific and graphing calculators but not of days. Good lesson none the less.

    a bank produces two outputs utilising two inputs and has two processes. process 1 uses 4 units of A and two units of B produces 2units of Z. the capacities of A and B are400& and 600 respectively. assume the profit per unit for Y and Z are20. formulate the linear programming

    XYZ Steel Company manufactures two kinds of wrought-iron rails: Model E (the elegant) and Model D (the distinctive). Model E rails sell for $59 and cost $50 to make, whereas Model D rails sell for $48 and cost $41 to make. To make one Model E rail requires 2 hours on Machine A, 1 hour on Machine B, and 4 hours on Machine C. On the other hand, to make one Model D rail requires 1 hour on A, 2 hours on B, and 5 hours on C. Production scheduling indicates that during the coming week Machine A will be available for at most 30 hours. Machine B for at most 24 hours, and Machine C for at most 72 hours. Find the number of each kind of rail to be made in the coming week in order for the company to maximize its profit. What is this maximum profit? At the maximum, which machines, if any, are not fully utilized?
    Please do this one!

    The SHANIA NICOLE Furniture Company manufactures dining room tables andchairs. Each table requires 50 board feet and 3 hours of labor. Each chair takes 20board feet and 4 hours of labor. The manufacturer has 3,000 board feet of lumberavailable and a staff able to provide 380 hours of labor. Finally, the manufacturer hasdetermined that there is a net profit of P100 for each chair sold and P200 for everytable sold. For simplicity, we assume that needed materials such as nails andvarnish are available in sufficient quantities. How many tables and chairs should thecompany manufacture in order to maximize its profit assuming that each itemmanufactured is sold?

    A dietician wishes to mix types of foods in such a way that vitamin contents of the mixture contain at least 8 units of vitamin A and 10 units of units of vitamin C. Food ‘I’ contains 2 units/kg of vitamin A and 1 unit per kg of vitamin C. Food ‘II’ contains 1 units/kg of vitamin A and 2 units per kg of vitamin C. It costs PHP 400 per kg to purchase Food ‘I’ and PHP 740 per kg to purchase Food ‘II’. Formulate as a linear programming problem to minimize the cost of such mixture. Determine the Optimal Solution.... Hello ma'am 👋can you help me too? To determine the constraints on this problem?

      Objective function (cost): 400x + 740y, where x = number of kg of food one, and y = number of kg of food 2. Constraints: 2x+y >= 8, x+2y>=10.
