Need help with the attached problem:
A consumer is in equilibrium at point A in the accompanying figure. The Price of good X is \$5.
a.What is the price of good Y?
b.What is the consumer's income?
c.At point A, how many units of good X does the consumer purchase?

#### Solution Preview

The most important information given here is the price of good X is \$5, and the budget line ends at quantity 20 on the X axis. This means if the consumer spends all the income on good X he get 20 units. At \$5 a piece that translates to \$100. Hence the income of the person is \$100.

a. Once we have the income it is easy to find ...
