In constructing indifference curves,
A)the concept of cardinal utility is assumed.
B)the marginal rate of substitution is assumed to be increasing.

B)where MUX/MUY = PX/PY.
C)where producer equilibrium is attained.
D)when a and b are both correct.
7

8

Production isoquants

B)cannot intersect.
C)can intersect.
D)a and b.
E)a and c.
9
