Marked out of 1.00 Flag question Question text Refer to the diagram above: An activity level of 350 is associated with Select one: a. Total benet equals total cost, but the amount of the activity is too high. The optimal choice is below the break-even point. b. Breaking even, where total benet equals total cost. This is the optimal choice of activity level. c. M C >M B , and so the optimal level of the activity is therefore too low. More of the activity should be pursued; doing so will equate MC and MB. d. the maximum amount of total benet, and net benet as well.
