Josh has decided to take a course at the local community college that could help him get a promotion at work. The course begins at 5 p.m. and goes until 9 p.m. on Monday nights. Josh normally works until 5 p.m. each day, but because of the drive time to the community college, he will need to leave work at 3 p.m. on class days. Josh currently earns $18.50 per hour. His employer contributes 10% of Josh's gross earnings to a 401(k). If the class meets 16 times, what is Josh's total opportunity cost for the class?
