The PENTEL Corporation manufactures three different types of computer chips. Each type of chip requires different amounts of processing time in three different departments as summarized in the following table. Processing Hours Required per 100 Chips Chip A Chip B Hours Available Chip C Dept 1 3. 2 4 10,000 Dept 2 2 4 3 9,000 Dept 3 3 4 2 11,000 The total profit (in dollars) for each type of chip may be described as follows: Chip A profit = -0.36A + 8.29A + 540 Chip B profit = -0.6182 + 9.468 + 1,108 Chip C profit = -0.48C + 11.00C + 850 where A, B, and C represent the number of chips produced in 100s. (a) Formulate an NLP model for this problem to maximize profit (in dollars). MAX: Subject to: department 1 department 2 department 3 A, B, C, 0 (b) Implement your model in a spreadsheet and solve it. What is the optimal solution? (Round your numerical values to two decimal places.) (A, B, C) =
