Explanation of Solution
Solution:
Let,
The size mix and cost of the valves given in the tale below,
Supplier |
Cost Per value (S) |
Percent Large |
Percent Medium | Percent Small |
1 | 5 | 40 | 40 | 20 |
2 | 4 | 30 | 35 | 35 |
3 | 3 | 20 | 20 | 60 |
Then, the total cost of the valves can be expressed as,
In each month, at least 500 large valves should be purchased. Therefore, the constraint can be written as,
In each month, at least 300 medium valves should be purchased. Therefore, the constraint can be written as,
In each month, at least 300 small valves should be purchased. Therefore, the constraint can be written as,

- Which option is correct for the following system equation? x-y-z=4 2x-2y-2z=8 5x - 5y - 5z = 20 answer a)Finite solutions b)No solution c)Subzero solutions d)Infinitely many solutions e)Unique solutionarrow_forwardSolve the following exercise using jupyter notebook for Python, to find the objective function, variables, constraint matrix and print the graph with the optimal solution. A farm specializes in the production of a special cattle feed, which is a mixture of corn and soybeans. The nutritional composition of these ingredients and their costs are as follows: - Corn contains 0.09 g of protein and 0.02 g of fiber per gram, with a cost of.$0.30 per gram.- Soybeans contain 0.60 g of protein and 0.06 g of fiber per gram, at a cost of $0.90 per gram.0.90 per gram. The dietary needs of the specialty food require a minimum of 30% protein and a maximum of 5% fiber. The farm wishes to determine the optimum ratios of corn and soybeans to produce a feed with minimal costs while maintaining nutritional constraints and ensuring that a minimum of 800 grams of feed is used daily. Restrictions 1. The total amount of feed should be at least 800 grams per day.2. The feed should contain at least 30% protein…arrow_forwardYou are given some tasks of size xK, yK and zK respectively and there are at most 9 tasks each. Determine the best that you could achieve if you are to fill up a hole of size SK, for the following values of x, y, z and S, by maximizing the space used (up to S), i.e. minimizing the used space, if any. Show how many tasks of size x, how many tasks of size y and how many tasks of size z are used in each of the three cases. (g) Now if we relax the requirement so that there are no upper limits on the number of tasks for each type, determine the maximal space usage and the task mix. (h) If we tighten the requirement so that there are still at most 9 tasks of each size, but we also require that each type of tasks must be used at least once, determine maximal space usage and the task mix.
