i need a graphical solution explanation

Question #1 Acme food processing plant which manufactures hamburger buns and burger patties. They grind their own flour for the hamburger buns at a maximum rate of 200 kilograms per week. Each hamburger bun requires 0.1 kgs of flour. They currently have a contract with Seawood, Inc. which specifies that a delivery of 800 kgs of meat product is delivered every Monday. Each hamburger patty requires 14 kgs of minced meat. All the other ingredients in the hamburger patties and hamburger buns are in plentiful supply. Finally, the labor force at Acme consists of 5 employees working full time (40 hours per week each). Each hamburger patty requires 3 minutes of labor, and each hamburger bun requires 2 minutes of labor. Each hamburger patty yields a profit of $0.20, and each hamburger ban yields a profit of $0.10. Acme would like to know how many hamburger patties and how many hamburger buns they should produce each week so as to achieve the highest possible profit. (a) Formulate a linear programming model for this problem. (b) Use the graphical method to solve this model
