The individual's total happiness is measured by the sum of period utility across time,u(c1) + u(c2). Let u(c) be an increasing function that is strictly concave in the amountof consumption c enjoyed by the individual. Also assume that the function u(c) satisfiesthe Inada condition lim→0 u' (c)utility function u(c) with respect to c.= ∞ where u'(c)du(c)is the first-derivative of thedc1. The individual faces a budget constraint in period 1 of Pcı+s1 = Y and a period2 budget constraint of P2C2 = (1+r)s1. Interpret each of these two constraints inwords. Consider the problem of an individual that has Y dollars to spend on consuming overwo periods. Let c1 denote the amount of consumption that the individual would likeco purchase in period 1 and c2 denote the amount of consumption that the individualwould like to consume in period 2. The individual begins period 1 with Y dollars andcan purchase ci units of the consumption good at a price P and can save any unspentwealth. Use s1 to denote the amount of savings the individual chooses to hold at the endof period 1.Any wealth that is saved earns interest at rate r so that the amount of wealth thendividual has at his/her disposal to purchase consumption goods in period 2 is (1+r)s1.This principal and interest on savings is used to finance period 2 consumption. Again,for simplicity, we can assume that it costs P2 dollars to buy a unit of the consumptiongood in period 2.

How do you derive that the slope of a budget line is -p1/p2? I'd like to see the mathematical process. Thanks!
The graph of the budget line below has dollars on the vertical axis and food on the horizontal axis. Which statement is false? D 100 Food The vertical intercept represents all money available for purchasing. The distance OA shows the amount of money spent on OD amount of food. If the amount of money available is known in this graph, then the absolute and relative price of food is known also. The horizontal intercept represents all the food the consumer could purchase with the budget available.
