In an effort to reduce global warming, it has been proposed that a tax be levied based on the emissions of carbon dioxide into the atmosphere. Suppose the cost-benefit equation In (1-P)= -0.0038 -0.0054t estimates the relationship between the percent reduction of emissions of carbon dioxide P (as a decimal) and the tax t in dollars per ton of carbon dioxide. Use this information to answer parts (a) and (b) a. Solve the equation for t, giving t as a function of P. Graph the function. t= (Do not simplify. Type an exact answer. Use integers or decimals for any numbers in the expression.)
