We want to show that when a monopolist uses two-part pricing and faces identical consumers, charging...

a price higher or lower than the competitve price, P= 10 (with a lump-sum fee equal to consumer surplus), reduces the monopoly's prots. The gure to the rig ht shows the demand curve for a representative consumer. Determine the prots (per-unit prots + collected fee from the consumer) for each of the following per-unit prices. Assume xed costs are negligible. Prot from two-part pricing when price is p = 10 equals $|:|. (Round to two decimal places.) Prot from a two-part pricing when price is p = 30 equals $El. (Round to two decimal places.) Prot from a two-part pricing when price is p = 5 equals $|:|.
