horizontal
which of the following is true if the price elasticity of demand for a good is zero
the demand curve is vertical

unit-elastic
Assume there are 2 good, X and Y. Good X costs $5 and good Y costs $10. If your income I'd $200, which combinations of X and Y is on your budget line
0 units of good x and 20 units of good y
If a decrease from $2 to $1 causes an increase in quantity demanded from 100 to 120, price elasticity equals
0.27

A perfectly elastic supply curve is
Horizontal
The optimal consumption rule states that total utility is maximized when all income spent and
MU/P is equal for all goods
A consumer is spending all of her income and receiving 10 utility from the last unit of good A and 80 utility from the last unit of good B. If the price of good A is $2 and the price of good B is $1, to maximize total utilit the consumer should buy
More of good B
