1. Suppose the price of x1 is $20 and the price of x2 is $4. If good x1 is on the horizontal axis, what is the slope of the consumer's budget constraint?
a. -0.20
b. -0.25
c. -5.0
d. -0.2
e. -4.0
f. -20.0
2. Suppose the price of x1 is $5 and the price of x2 is $1 and Toni's income is $20. Suppose Toni gets a $5 gift card that can only be used for the purchase of x1 and there is no resale value of the gift card. With the gift card, the commodity bundle (1,20) is on Toni's budget constraint.
True
False
3. Tiffany's utility function is given by the formula U(x1, x2) = min{20x1, 10x2}. If x1 = x2, which commodity will have a greater marginal utility?
A. Both x1 and x2 have the same marginal utility
B. It is not possible to determine which commodity has higher marginal utility
