1. Linear programming. Clever Sporting Equipment, Inc. makes two types of balls: soccer balls and cork balls. The making of each soccer ball and cork ball requires 2 hours and 4 hours of production time, respectively. For the next month, total production hours of 800 are available. Also, the combined production quantity for these two balls must be at least 300 units in the coming month. Maximum monthly demand for soccer balls is known to be 350 balls. The objective for this linear programming model is to fulfill the given production requirements at a minimum cost for the total production. The production cost for each soccer ball is $9 and each cork ball is $7. Let S = number of soccer balls manufactured and C = number of cork balls manufactured.
(a) Formally state the problem.
(b) Graph the constraints and identify the feasible region. Place the number of soccer balls on the horizontal axis and let each grid line = 25 balls. Be sure to shade in the feasible region and label all intercept values on your constraints.
(c) The optimal production plan for this company is soccer balls and cork balls, and the resulting production cost for the coming month
is $ . Show all work that supports this choice in the space below.
(d) Perform the same linear programming problem in Excel and attach the answer report.
