If we have money, we buy goods and services to satisfy our needs. In economics, thesatisfaction that we get from the consumption of goods and services is called utility. Usea utility graph to explain what happen to the utility when you keep on increasing thenumber of units consumed. Also explain what happens to the utility when you keep onincreasing the number of units consumed. Also explain what happens to the additionalutility (i.e. additional satisfaction) when you increase your consumption by one unit

2. Charlie consumes apples (A) and bananas (B). His utility function is . The price
of apples is $1, the price of bananas is $2, and Charlie’s income is $40. The price of bananas
suddenly falls to $1.
(a) Before the price change, how many apples and bananas did Charlie consume?
(b) After the price change, how many apples and bananas did Charlie consume?
(c) If after the price change, Charlie’s income had changed so that he could only attain his
original level of utility, how many apples and bananas would he have consumed?
(d) What are the magnitudes of the price, substitution, and income effects for the
consumption of bananas?

- Take Jeremys total utility information in Exercise 6.1, and use the marginal utility approach to confirm the choice of phone minutes and round trips that maximize Jeremys utility.arrow_forwardJeremy is deeply in love with Jasmine. Jasmine lives where cell phone coverage is poor, so he can either call her on the land-line phone for five cents per minute or he can drive to see her, at a round—trip cost of 2 in gasoline money. He has a total of 10 per week to spend on staying in touch. To make his preferred choice, Jeremy uses a handy utilimometer that measures his total utility from personal visits and from phone minutes. Using the values in Table 6.6, figure out the points 011 Jeremys consumption choice budget constraint (it may be helpful to do a sketch) and identify his utility-maximizing point.arrow_forwardWould you expect total utility to rise or fall with additional consumption of a good?

- 1. A consumer has an income of $3024 to spend each day. The only two goods the consumer is interested in purchasing are goods A and B. The marginal-utility schedules for these two goods are shown in the table below. The price of B does not change and is $378. The marginal utility per dollar from B is also shown in the table. But the price of A varies as shown in the table. The marginal utility per dollar from A when the price of A is $1512 and $756 is shown in the following table. Good A Good B Quantity MU MU/$1512 MU/$756 MU MU/$378 1 24 2 15 3 12 4 8 5 6 6 4 48 32 24 16 8 4 ||||| ||||| |||arrow_forward4. Liam initially has a weekly allowance of €24 to spend on eggs (at €0.40 per egg) and beans (at €0.80 per tin). Liam will only consume 4 eggs with each tin of beans and never changes this proportion. (a) What is the utility maximising amount of eggs and beans that Liam buys each week? (b) Suppose the price of eggs rise to €0.60 per egg but the price of beans falls to €0.60 per tin. At the same time, Liam's weekly allowance rises to €30. How much of each good will Liam now buy? Compare your answer to that in (a) and explain the difference, if there is one. Use a diagram to complement your answer.arrow_forwardLee has calculated her marginal utility from buying pizza slices and soda (shown on the table in the worksheet) and wants to use these data to decide how to rationally spend the money she has. The price of pizza is $2.00 and the price of soda is $2.00 question 9 (a) given these prices and your worksheet calculations, what is the first product lee will buy? (b) would lee ever buy four slides of pizza? Why/why not? question 10Given the data in your worksheet, how many pizza slices and sodas lee should buy to maximize her total utility if she rationally spends her budget of 10.00? question 11 when the price of pizza changes, lee's MU/$P changes. If the price of pizza decreases to $1.50 and her budget decreases to $7.50, how many pzza slices and sodas lee should buy to maximize her total utility?arrow_forward
