Davison Electronics manufactures three LED television monitors, identified as Model A, Model B, and Model C. Davison Electronics four manufacturing plants. Each model has its lowest possible production cost when produced at Plant 1. However, Plant 1 does not have the capacity to handle the total production of all three models. As a result, at least some of the production must be routed to the other manufacturing plants. The following table shows the minimum production requirements for next month, the plant capacities in units per month, and the production cost per unit at each plant:

Anecdotally, entrepreneurs frequently encounter two critical dilemmas in managing human resources: the timing of hiring and the decision regarding hiring a generalist versus a specialist for their growing venture. Deciding when to expand a team is crucial, as premature hiring (i.e., hiring too soon) can strain resources, while delayed hiring (i.e., hiring too late) might hinder growth opportunities. Moreover, the choice between hiring a generalist or a specialist depends on the specific needs and stage of the venture, with each option presenting distinct advantages and challenges. To address these issues, a management scholar seeks to identify the factors shaping the hiring cycle throughout the entrepreneurial journey and to understand the criteria for choosing between generalists and specialists at various stages of a venture. The scholar has assembled a sample of 20 experienced South African entrepreneurs who have encountered both failure and success in the financial technology…

- PS.53 Brother I.D. Ricks is a faculty member at BYU-Idaho whose grandchildren live in Oklahoma and California. He and his wife would like to visit their grandchildren at least once a year in these states. They currently have one vehicle with well over 100,000 miles on it, so they want to buy a newer vehicle with fewer miles and that gets better gas mileage. They are considering two options: (1) a new subcompact car that would cost $18,750 to purchase or (2) a used sedan that would cost $12,750.They anticipate that the new subcompact would get 37 miles per gallon (combined highway and around town driving) while the sedan would get 26 miles per gallon. Based on their road tripping history they expect to drive 13,000 miles per year. For the purposes of their analysis they are assuming that gas will cost $2.93 per gallon.Question: How many miles would the Ricks need to drive before the cost of these two options would be the same?
