Suppose the market for medicinal herbs (x1) and orange juice (x2) has only two consumers

Adam and Barbara. Suppose Adam and Barbara's utility functions are both Cobb-Douglas and

identical: u(x1,x2) = x1x2

. Their incomes are denoted by mAand mB, respectively.

What is the market demand for orange juice?

a. X2= 0.5 ( mA+ mB) / p2

b. X2= ( mA+ mB) / (p1 + p2)

c. X2= 0.5 ( mA+ mB) * p2

d. X2= 0.5 mB/ p2

e. X2= 2 ( mA- mB) / p1
