A baker makes cakes and sells them at county fairs. Her initial cost for the Pointe Coupee parish fair was $40.00. She figures that each cake costs $2.50 to make, and she charges $6.50 per cake. Let x represent the number of cakes sold. (Assume that there were no cakes left over.)

(a) Express the cost C as a function of x, where x represents the number of items described.
(b) Express the revenue R as a function of x.
(c) Determine analytically the value of x for which revenue equals cost.
(d) Graph y1 = C(x) and y2 = R(x) on the same xy-axes and interpret the graphs.
