Budget Line: It is defined as the combination of all goods that a consumer can buy exhausting his all income. Formula for the budget line is:
Here,
is the quantity of good X. 
is the quantity of good Y. 
is the total income. 
is the price of good X. 
is the price of good Y.
is the marginal utility. 
is the total utility. - X is the quantity of any good.
- N is the number of goods.
is the marginal utility per dollar. 
is the price of good X. 
is the marginal utility of good X. 
is the marginal utility of good Y. 
is the price of good X. 
is the price of good Y.
Or
Here,
Marginal Utility per dollar: It is the ratio of marginal utility to that of the price of a good. The formula to calculate the marginal utility per dollar is:
Here,
Maximizing utility in the case of two goods: It states that the equilibrium level of consumption of two goods for a consumer is achieved when the marginal utility per dollar of the two goods are equal. This means that the following conditions must be fulfilled:

1. Imagine a society that produces military goods
and consumer goods, which we'll call "guns"
and "butter."
a. Draw a production possibilities frontier for
guns and butter. Using the concept of
opportunity cost, explain why it most likely
has a bowed-out shape.
b. Show a point that is impossible for the
economy to achieve. Show a point that is
feasible but inefficient.
c. Imagine that the society has two political
parties, called the Hawks (who want a strong
military) and the Doves (who want a smaller
military). Show a point on your production
possibilities frontier that the Hawks might
choose and a point the Doves might choose.
d. Imagine that an aggressive neighboring
country reduces the size of its military. As a
result, both the Hawks and the Doves reduce
their desired production of guns by the same
amount. Which party would get the bigger
"peace dividend," measured by the increase in
butter production? Explain.
A health study tracked a group of persons for five years. At the beginning of the study, 20%were classified as heavy smokers, 30% as light smokers, and 50% as nonsmokers. Resultsof the study showed that light smokers were twice as likely as nonsmokers to die duringthe five-year study, but only half as likely as heavy smokers.A randomly selected participant from the study died during the five-year period. Calculatethe probability that the participant was a heavy smoker
