One week, Kevin earned $492.00 at his job when he worked for 20 hours. If he is paid the same hourly wage, how much would he make the next week if he worked 3 hours?

If Kevin earned $492.00 for 20 hours, then his hourly wage is $492.00/20 hours = $<<492/20=24.60>>24.60/hour.

If he worked for 3 hours, then he would earn 3 hours * $24.60/hour = $<<3*24.6=73.8>>73.8. Answer: \boxed{73.8}.
