Chocolate Syrup (cups) 10 5 0 5 Mustard (gallons) 4) Robert's preferences are shown in the diagram above 10 Suppose that Robert has $96. The price of Mustard is $24/gallon, and the price of Syrup is $12/cup. Suddenly the price of Mustard falls to $12/gallon. a) Show the Income and Substitution effects of this change on the diagram. b) Is Robert better off? c) At the new prices, how much money does Robert need to be as happy as he was initially? d) What is the most that Robert is willing to pay to induce the Mustard seller to reduce the price from $24/gallon to $12/gallon?

Suppose that with a budget of $210, Fatima spends $126 on sushi and $84 on bagels when sushi costs $2 per piece and bagels cost $2 per bagel. Then, after the price of bagels falls to $1 per bagel. Instructions: Enter your answers as a whole number. How many pieces of sushi and how many bagels did Fatima consume before the price change? pieces of sushi and bagels At the new prices, how much money would it have cost Fatima to buy those same quantities (that is, the quantities that she consumed before the price change)? Given that it used to take Fatima's entire $210 to buy those quantities, how big is the income effect caused by the lower price of bagels?

12. Five consumers have the following marginal utility of apples and pears: Marginal Utility Marginal Utility of Apples of Pears Claire 6 12 Phil 6 6 Haley 6 3 Alex 3 6 Luke 3 12 The price of an apple is $1, and the price of a pear is $2. Which, if any, of these consumers are optimizing their choices of fruit? For those who are not, how should they change their spending?

Consider the increase in the price of a can of soda and assume that soda is a normal good. Describe how the income and substitution effects impact on the demand for the cola if its price increases. Also describe how these two effects interact for inferior goods if there is a fall in the price of the good. Use bullet points

Consider the two questions about utility. The table refers to the first question only. Tod loves to travel, and he takes several river cruises per year. The table contains information about the utility Tod gets from the river cruises. Number of river cruises Total utility Marginal utility 0 0   1 12 12 2 20 8 3 25 5 From this information, it can be concluded that the number of river cruises Tod takes is indeterminable without knowing Tod’s income or the price of the cruises. that total utility is maximized when Tod takes one river cruise. that Tod will take two river cruises. that Tod will take three river cruises. Suppose that Jim has $4 to spend on a snack and that the only thing available is tea and scones. Jim’s marginal utility of the first cup of tea is 30 and his marginal utility of the second cup of tea is 20. Each cup of tea costs $1. Jim’s marginal utility of the first scone is 80 and his marginal utility of the second scone is 60. Each scone costs…
