Monica has decided that she wants to build enough retirement wealth that, if invested at 8 percent per year, will provide her with $4,400 of monthly income for 20 years. to date, she has saved nothing, but she still has 25 years until she retires.

how much money does she need to contribute per month to reach her goal? (do not round intermediate calculations. round your final answer to 2 decimal places.)

Firms like papa john’s, domino’s, and pizza hut sell pizza and other products that are differentiated in nature. while numerous pizza chains exist in most locations, the differentiated nature of these firms’ products permits them to charge prices above marginal cost. given these observations, is the pizza industry most likely a monopoly, perfectly competitive, monopolistically competitive, or an oligopoly industry?
