A consumer with a weekly budget of $20 can choose between two international calling plans. The first plan has no sign-up costs and charges 5c per minute of conversation, the second plan charges a flat weekly fee of $5 and zero cents per minute.

Draw a diagram where you measure minutes of conversation along the horizontal axis and money for other items along the vertical axis and illustrate the consumer’s budget line under the first plan.

Under the first plan the consumer makes 90 minutes of calls each week. In your diagram, add a generic indifference curve to illustrate the consumer’s optimal bundle under the first plan.

Now, add to your diagram the consumer’s budget line under the second phone plan. What is the slope of this second budget line?

Which plan does your consumer prefer? Discuss.

Suppose the consumer considered international calls a perfect complement to all other activities, would the consumer still prefer the same plan? Discuss.

In your diagram, show the highest flat fee the consumer is willing to pay each week to use the second phone plan.

A consumer is trying to decide between two long-distance calling plans. The first one charges a flat rate of 10 cents per minute. The second charges a flat rate of 99 cents for calls up to 20 minutes in duration and then 10 cents for each additional minute exceeding 20. (Assume that calls lasting a non-integer number of minutes are charged proportionately to a whole-minutes charge). If the duration of a randomly selected call of this consumer is exponentially distributed...

A consumer is trying to decide between 2 long-distance calling plans. The first one charges a flat rate of 10 cents/min, while the second charges a flat rate of 99 cents for calls up to 20 minutes and then 10 cents for each additional minute exceeding 20 minutes (assume that calls lasting a noninteger number of minutes are charged proportionally, e.g. 6 seconds is 1/10 of a minute and so 6 seconds over 20 minutes would be charged 1 cent)....

20) A borrower is purchasing a property for $180,000 and can choose between two possible loan alternatives. The first is a 90% loan for 25 years at 9% interest and 1 point and the second is a 95% loan for 25 years at 9.25% interest and 1 point. Assuming the loan will be repaid in 5 years, what is the incremental cost of borrowing the extra money? A) 13.95% B) 13.67% C) 14.42% D) 12.39%. I know the answer is...

A consumer has an income R. She can choose between two goods: wine and beer. Lets assume the price of a glass of wine (Pw) is three and the price of a glass of beer (Pb) is two. We denote the consumption of wine as Xw and the consumption of beer Xb Write the budget constraint of the consumer. Compute the slope of the budget line and represent it on a graph. The following tables give the different bundles of...

1.A company can choose one of two investment plans, A and B. Under plan A, it can invest $117604 at 6.7% p.a., compounded monthly. Under plan B, it can invest $x at 6.2% p.a., compounded continuously. If the company wants to have the same amount after two years using either plan, what is the value of x ? (Give your answer correct to two decimal places.) 2.What is the extra amount of interest earned, if $3516 is invested for six...

A consumer can choose between goods X and Y. The consumer's utility function is: U=5X2Y2 Use following notation, as we have in class: Price of X = PX, Price of Y = PY, Income = I, the Lagrange multiplier = λ If PX= 20, PY = 5, and I = 400, what is the optimal amount of X that will maximize the consumer's utility subject to these prices and income? what is the optimal amount of Y that will maximize...
