今天与明天的消费以利率为交换比率，预算线以负一加 r 为斜率通过收入禀赋点，其两个截距分别是全部收入的现值和终值。

5. The budget equation
With m1 100, m2 63, r 10 percent, which statement of the budget is correct?
6. The two intercepts
Same consumer, what are the maximum possible c1 and c2?
7. Classifying the position
A consumer with endowment (100, 63) chooses c1 equal to 80. What is she and what does the account show?
8. Present value as a ranking
Why do analysts of all preference stripes rank payment streams by present value at the market rate?

With m1 100, m2 63, r 10 percent, compute the present value of income, rounded to two decimals, and write the number.
10. Savings compounded
Same consumer saves 20 in period one, compute the extra period-two consumption this funds, and write the number.

With m1 of 100, m2 of 63 and r of 10 percent, what is the maximum possible c2?
12. The lender's second period
The consumer with endowment (100, 63) at r of 10 percent chooses c1 of 80. What is c2?
13. Ranking streams by the market's ruler

A consumer whose endowment exceeds her period-one consumption is described how, and what does the bank account show?
