So, first, you have to determine what he makes per hour to make this as easy as possible. You need to first do 396 divided by 18, which gives you 22. He makes 22$ an hour. Next, now that you know what he makes, you can do 198 divided by 22, and that'll show how long he has to work to make that amount of money.
Hope this helped. Please mark this brainliest if you think this helped. Let me know if you need anymore help and I am more than happy.
