Time vs return: You have a part-time job conducting public interviews. You find that a political interview takes 55 min. and a market interview takes 45 min. You need to minimize the time you spend doing interviews to allow more time for your full-time job. The rules to keep the part-time job are as follows: You must complete at least 8 interviews each week. Also, you must earn at least $60 a week of which you earn $10 from each political interview, and $8 from each market interview. You also have the restriction that you must earn at least 40 bonus points per week of which 5 come from political interviews and 6 come from market interviews. How many interviews of each should you do each week to minimize the time you spend. Be specific, explain your logic and show all your work.
