Suppose that Marr's utility function for Wegmans' ice cream (W) and Tops' ice cream (T) is U= W+T. The price of Wegmans' ice cream is $5 and the price of Tops' ice cream is $4. Mary has 100$ to spend. Find the optimal bundle that maximizes Mary's utility. Show that Mary's optimal consumption bundle on a graph that shows her budget line and indifference curves. Specify the values of the y-intercept and x-intercept of the budget line.
