A company offers ID theft protection using leads obtained from client banks. Three employees work $40$ hours a week on the leads, at a pay rate of $$15$ per hour per employee. Each employee identifies an average of $3,600$ potential leads a week from a list of $4,700.$ An average of $7$ percent of potential leads actually sign up for the service, paying a one$-$time fee of $$80.$ Material costs are $$1,400$ per week, and overhead costs are $$9,000$ per week.

Calculate the multifactor productivity for this operation in fees generated per dollar of input. $($Round your answer to $2$ decimal places.$)$
