Acolor TV requires 3 sq yd of storage space, and a VCRrequires 1 sq yd of storage space. The sale of a color TVearns Highland a profit of $150, and the sale of a VCR earnsHighland a profit of $100. Highland has set the followinggoals (listed in order of importance):Goal 1 A maximum of $20,000 can be spent on purchasing color TVs and VCRs.Goal 2 Highland should earn at least $11,000 in profitsfrom the sale of color TVs and VCRs.Goal 3 Color TVs and VCRs should use no more than 200sq yd of storage space.Formulate a preemptive goal programming model that Highland could use to determine how many color TVs and VCRsto order. How would the preemptive goal formulation be modifiedif Highland’s goal were to have a profit of exactly $11,000?
- When answering questions on a survey, Melanie prefers to answer questions that allow her to write her own responses, so she is free to answer in any way that she'd like, rather than just pick a number.
