At what price would the total expenditure on jellybeans have been largest? P = $1 Q = $100 000 . B = $50 000 Qd = A - BP 100 000 = A - 50 000 (Add 50 000) A = 150 000 Qd= 150 000 - 50 00OP Ed = -B*(P/Q) -1 = - 50 000 (P/150 000 - 50 00OP) 150 000 - 50 00OP = 50 000P (Collect like terms, and then divide 100 000 from each side)
