Question 14

Suppose that you have $100 today and expect to receive $100 one year from today.Your money market account pays an annual interest rate of 25%,and you may borrow money at that interest rate.Suppose that you borrow $60 and spend $160 today.After you repay your loan one year from today,how much money will you have available for consumption one year from today?

Question 15

Figure 21-2.The graph shows two budget constraints for a consumer. 
-Refer to Figure 21-2.Suppose Budget Constraint B applies.If the consumer's income is $90 and if he is buying 5 light bulbs,then how much money is he spending on hamburgers?

Accepted Answer

If income is $90,then the price of a light bulb is $90/15 = $6.He is then spending ($6)(5)= $30 on light bulbs,so he is spending $90 - $30 = $60 on hamburgers.(The price of a hamburger is $90/9 = $10 and he is buying 6 hamburgers. )

Accepted Answer

A)   each point on a demand curve represents an optimal choice point.
B)   consumers purchase more inferior goods than normal goods.
C)   increases in income cause the budget constraint to rotate inward along one axis,which changes the consumer's purchases.
