Answer:
The consumer's income is $216.
Explanation:
A consumer consumes two goods Z and B.
The price of good B is $6.
The consumer is consuming 18 units of good Z and 0 units of good B.
The marginal rate of transformation is the ratio of the price of two goods.
The marginal rate of transformation is -2.
MRT = [tex]\frac{Pz}{Pb}[/tex]
2 = [tex]\frac{Pz}{6}[/tex]
Pz = 12
The budget constraint will be
= [tex]12\ \times\ 18\ +\ 6\ \times\ 0[/tex]\
= $216
