$17.$A college student has two options for meals: eating at the dining hall for

$$6$

per meal, or eating a Cup O$\text{'}$ Soup for

$$1\mathrm{.}50$

per meal. His weekly food budget is

$$60$

a$.$ Draw the budget constraint showing the trade$-$off between dining hall meals and Cups O$\text{'}$ Soup. Assuming that he spends equal amounts on both goods, draw an indifference curve showing the optimum choice. Label the optimum as point A$.$ b$.$ Suppose the price of a Cup O$\text{'}$ Soup now rises to

$$2$

Using your diagram from part $($a$),$ show the consequences of this change in price. Assume that our student now spends only $30$ percent of his income on dining hall meals. Label the new optimum as point
