Use a graphing calculator to plot the data and find the quadratic function of best fit.
-The following data represents the total revenue, R (in dollars), received from selling x bicycles at Tunney's Bicycle Shop.
Using a graphing utility, find the quadratic function of best fit using coefficients rounded to the nearest hundredth. $$\begin{array} { c | c } \text { Number of Bicycles, x } & \text { Total Revenue, R (in dollars) } \\\hline 0 & 0 \\22 & 27,000 \\70 & 46,000 \\96 & 55,200 \\149 & 61,300 \\200 & 64,000 \\230 & 64,500 \\250 & 67,000\end{array}$$
