a. Suppose == 2.Further assume that the prices of the two inputs are w1= $8 and w2= $3, respectively.What is the minimum cost to produce 140 units?

b. Now suppose = 3 and = 2.Further assume that the prices of the two inputs are w1= $8 and w2= $3, respectively.How much output can be produced for $600?

c. Between (a) and (b) has the firm become more or less efficient? Explain
