(Scenario: e-Books and Sports Tickets) Look at the information provided in the scenario e-Books and Sports Tickets. Suppose Phillip discovers that if he spends all of his money on sports tickets, he can buy more sports tickets than he could previously because something changed. This is a result of: O A. a decrease in the price of e-Books. O B. a decrease in the price of tickets. O C. an increase in the price of e-Books. O D. an increase in the price of tickets.

1. An individual's budget Suppose Darnell has a weekly budget of $32 to spend on ranch dressing and spinach. Ranch dressing is priced at $4 per bottle, and spinach is priced at $2 per container. If Darnell spends his entire $32 on ranch dressing, he can buy 16 containers of spinach. 8 bottles of ranch dressing. If he spends his entire $32 on spinach, he can buy Use the blue line (circle symbol) to plot Darnell's budget constraint on the following graph. Next, use the orange point (square symbol) to shade the area that represents combinations of ranch dressing and spinach that are affordable for Darnell. Finally, place the black point (plus symbol) on the point on Darnell's budget constraint that corresponds to a scenario in which Darnell spends $16 on each good. Note: Dashed drop lines will automatically extend to both axes.
1. Muhammad enjoys going to the aquarium (x) and playing basketball (y). His preferences on x and y are described by his utility function: U(x, y) = 100x23y3. He has a budget of £120 per week to spend on playing basketball and going to the acquarium. Knowing that p,=10 and py=10: ,2/3,1/3 (A) Find the optimal combination of x and y so that Muhammad maximizes his utility subject to the budget constraint. Show this graphically. (B) Consider now that the price of going to the aquarium increases to £20, the price of playing basketball is now £15 and the income did not change. How does this modify Muhammad's optimal bundle? Show this graphically. (C) Compare the optima in (A) and (B): has the valuation of y in terms of x changed? Explain.
1. An individual's budget Suppose Musashi has a weekly budget of $24 to spend on juice and yogurt. Juice is priced at $2 per gallon, and yogurt is priced at $6 per container. If Musashi spends his entire $24 on juice, he can buy gallons of juice. If he spends his entire $24 on yogurt, he can buy containers of yogurt. Use the blue line (circle symbol) to plot Musashi's budget constraint on the following graph. Next, use the orange point (square symbol) to shade the area that represents combinations of juice and yogurt that are affordable for Musashi. Finally, place the black point (plus symbol) on the point on Musashi's budget constraint that corresponds to a scenario in which Musashi spends $12 on each 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.

John likes Coca-Cola. After consuming one Coke, John has a total utility of 10 utils. After two Cokes, he has a total utility of 25 utils. After three Cokes, he has a total utility of 50 utils. Does John show diminishing marginal utility for Coke or does he show increasing marginal utility for Coke? Suppose that John has $3 in his pocket. If Cokes cost $1 each and John is willing to spend one of his dollars on purchasing a first can of Coke, would he spend his second dollar on a Coke, too? What about the third dollar? If John’s marginal utility for Coke keeps on increasing no matter how many Cokes he drinks, would it be fair to say that he is addicted to Coke? *use tables and/or graphs if possible, please original work

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
5. Leila currently buys 6 trips using public transportation with a marginal utility of 2, and 4 trips using ride-share with a marginal utility of 8. Suppose that the price of a trip through public transport is 12 and the price of a trip through ride share is 56. Is Leila currently maximizing her utility? Explain why or why not. If not, what is the optimal action to improve her utility?
4. 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.
