Problem
Consider a driver's decision regarding how fast to drive. In particular, suppose that for this driver, the benefit (ins) of driving x miles per hour (mph) above the speed limit usually is B(x) = 63x - 2x^3. Also, the driver views the cost (ins) of speeding as C(x) = 1.5x^2. First, determine by how much this driver will choose to exceed the speed limit (x*). Second, sketch marginal benefit and marginal cost on a graph to illustrate your result. You will not lose points if your graph is not numerically accurate, as long as MB and MC have the correct shape.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
