Esmeralda is a fortune-teller and can predict her clients' futures. The demand for future-telling sessions is given by yD=20-p, where y is the number of client sessions, and p is the price per session. Her future-telling costs increase more than proportionally with each session(she gets horrible headaches after a while); her cost function is C(y)=y^2(the square of y)

Assume that Promised Land drops the unifo rm price requirement. Assume further that E smeralda can not only tell the future but als o read customers' minds, and see exactly ho w much each customer is willing to pay, at m ost, for each session. That is, she knows all t heir willingness to pay. What profit will she make? A 111.11 B 66.67 C 44.44 D 155.55
