Tan has 184.2 dollars to spend on two goods, good 1 and good 2. Let x1 and x2 denote respectively the quantity of good 1 and the quantity of good 2. The price of good 1 is 7.5 and the price of good 2 is 5.5. Suppose that the government subsidizes all consumers of good 2 by 2 dollars per unit on every unit of good 2 each person buys but only if the amount of good 2 exceeds 10 units. If Tan buys x1 = 7.2 units of good 1, what is the maximum amount of good she can buy
