If you work a job for 40 hours per week at (w) dollars an hour, how much will you make in a year?

Assuming working week = 5 days
Working hours in a week = 40 hours
$ per hour = w
$ earned per week = 40 * w = 40w

In a year, there are 52 weeks.

So, amount earned in a year will be:

40w * 52 = 2080w
