b. The optimal level of activity is ______ units of activity where ______ (TB, TC, MB, MC, NB) reaches its maximum value of $_________.
c. Because TB is maximized at 100 units of activity, a line drawn tangent to the TB curve at 100 units of activity (not shown in the figure) has a slope of ______. NB at 100 units of activity is $_________, which is identical to the value of NB at ______ units of activity. Beyond 100 units, NB is _____________ (positive, rising, zero, negative).
d. At 25 units of activity, ______ (TB, TC, MB, MC, NB) is rising faster than ______ (TB, TC, MB, MC, NB) is rising, and thus ______ (TB, TC, MB, MC, NB) is rising.
e. At 75 units of activity, decreasing the activity causes ______ (TB, TC, MB, MC, NB) to fall faster than ______ (TB, TC, MB, MC, NB) falls, and thus ______ (TB, TC, MB, MC, NB) rises.
