I'm a bit confused on some intermediate piecewise questions.

A job pays time and a half for overtime(anything worked over 40 per week). Your hourly rate is 16.00$ per hour.

I've found the first two, 16x if x is less than or equal to 40 and 640+24(x-40) if x > 40.

How do I find out how many hours they have to work in order to receive $1,200 per week(besides guessing the hours and run it through a calculator).

And secondly, If he wants to make that amount, but limit his weekly hours to a maximum of 60 hours per week, and will need to ask for a raise to meet that, how much does he ask for? I don't understand what to use for an equation at that point.

Thanks in advance!
