Choose and explain your answer thoroughly with math--graphical, algebraically, numerically.

The firm depicted inFigure 6-10currently is producing 200 units of output per day. If it decides to increase its output level to 375 units, then it will:

a. adjust from point F to point G in the short run

b. be unable to adjust to point G in the short run because some inputs are fixed

c. be unable to adjust to point G in the long run because some are fixed

d. be unable to adjust to point H in the short run because some inputs are fixed

e. adjust from point F to point H in the long run
