Question

A farmer can buy two types of plant food, mix A and mix B. Each cubic yard of mx A contains 54 pounds of phosphoric acid, 28 pounds of nitrogen, and 6 pounds of potash Each cubic yard of mix B contains 12 pounds of phosphoric acid, 24 pounds of nitrogen, and 18 pounds of potash The minimum monthly requirements are 540 pounds of phosphoric acid, 840 pounds of nitrogen, and 270 pounds of potash Find the set of feasible solutions graphically for the amounts of mix A and mix B that can be used #xis the number of cubic yards of mix A used and y is the number of cubic yards of mix B used, write a system of linear inequalities that indicates appropriate restraints on x and y. Write an inequality for the constraint on phosphoric acid Complete the inequality below 20- 540 Write an inequality for the constraint on nitrogen. Complete the inequality below 840 Write an inequality for the constraint on polash Complete the inequality below 270 Are any other inequalities needed? Click the graph, choose a tool in the palette and follow the instructions to create your graph

Explanation / Answer

Constraint on phosphoric acid:
54x+28y>=540
Constraint on Nitrogen:
28x+24y>=840
Constraint on potash:
y*18>=270

Other inequalities:
Option C
Yes,x>=0,y>=0
