Each week you buy the sam

Each week you buy the same exact cart full of items from the grocery store. The prices have not changed in years, and each week your groceries cost $100. You are buying the optimal bundle, and can’t possibly get a higher utility with your $ 100 food budget.Suppose that one week the grocery store changes the price on each item in the store: some prices re increased, and some prices are secreased. As it turns out, if you were to buy the exact same cart of groceries you bought the previous weeks, your groceries would still cost exactly $100
