99 Myra drives a 1994 Honda Accord, the most stolen car in the United States. She can take precautionary actions to prevent her car from being stolen. The marginal benefit and marginal cost of these actions are MB = 10 ? 0.2A and MC = 2 + 0.64, where A is the number of precautionary actions. Myra values her car at $2,400. a. Graph Myra's MB and MC curves and show the optimal number of precau b. Suppose that Myra adds comprehensive coverage to her car insurance, wh: her $2,400 if her car is stolen. Using MB and MC curves, show Myra's opt precautionary actions
