You are given the followingdata:

Cost= C = $6,000.00

w=$50.00 per unit of labor

r=$50.00 per unit of capital

These data are used to construct the isocost line (C1) in the diagram to the right.

Suppose the wage increases to $75.00 but that the firm chooses to keep using the same amount of labor and capital to produce 200 units of output.

Given this new set of factor prices (w'=$75.00, r=$50.00), how much have costs changed if the set of input choices remains at pointA? $
