I need help on the following problem set:

Two consumers, Adam and Anna, both consume only two goods, Bananas (B) and Water ON). The price of bananas is $1/unit while the price of water is $0.5/gallon. Adam and Anna each have incomes of $200. For Adam, both Bananas and Water are normal goods and both are substitutes. For Anna, Water is a normal good but Bananas are inferior, and both are complements. 3) '3) Draw the budget constraint for either Adam or Anna (they are identical). Please put Water on the vertical axis and Bananas on the horizontal axis. Please label the slope and the intercepts. Suppose the incomes of Adam and Anna fall to $180 each. Continue your combined graph from (a) for both Adam and Anna. Draw the new budget lines (again same for Adam and Anna). Assume that Adam and Anna would have chosen the same bundle given the old budget of $200. Graphically show what the new optimal bundles for Adam and Anna look like. [You can assume that the indifference curves in the initial optimum look the same for Adam and Anna.] Remember that: For Adam, both Bananas and Water are normal goods and both are substitutes. For Anna, Water is a normal good but Bananas are inferior, and both are complements. Suppose the price of bananas increases to $2/unit. Draw two separate new graphs, one for Adam and one for Anna. Show graphically the change in consumption by Adam and Anna respectively. In each of the two graphs, show the substitution and income effects
