Economists use what is called a Leffer curve to predict the government revenue for tax rates from 0% to 100%. Economists agree that the end points of the curve generate 0 revenue, 10x(100-x) where R is revenue in millions at a tax 75+ x but disagree on the tax rate that produces the maximum revenue. Suppose an economist produces this rational function R(x) = rate of x percent. Use a graphing calculator to graph the function. What tax rate produces the maximum revenue? What is the maximum revenue? OA. 39.6%; $209 million. OB. 35.8%; $209 million OC. 37.5%; $210 million OD. 34.9%; $207 million
