One week, Magan earned $477.60 at his job when he worked for 24 hours. If he is paid the same hourly wage, how much would he make the next week if he worked 18 hours?

To find Magan's hourly wage, you divide his earnings by the number of hours worked, performing 477.60 / 24 = $<<477.60/24=19.90>>19.90/hour.

To determine how much Magan made in the next week, you multiply his wage by the number of hours he worked, performing 19.90 * 18 = $<<19.90*18=358.20>>358.20. Answer: \boxed{358.20}.
