Use the cost-benefit framework along with the relevant concepts (e.g. benefits, costs, net-benefit, opportunity cost), in your response. Consider a decision between 4 options. All of the options require the same amount of time and they are all affordable. Also assume that all of the benefits and costs of each option are accurately expressed in the dollaramounts given below. Here is the description of the 4 options: Option 1: benefits = $165, explicit costs = $45 Option 2: benefits = $110, explicit costs = $55 Option 3: net-benefit = $75 Option 4: economic surplus = -$37 Part A: Is Option 4 a good choice? Explain. Part B: What is the implicit cost of Option 1? Show your work. Part C: What is the economic surplus of Option 3? Part D: Which of the 4 options is the best use of time? Explain
