Joel earns $5.50 an hour and time-and-a-half for overtime. how much does he earn for a 44.5-hour week?

The expression which can be used to solve this problem is 5.50h + 1.5h. 

Since the given data is 44.5 hour week, all we need to do is substitute the given data to the expression. Since it takes 56 hours a week for a complete office/working hour without overtime, Joel's 44.5 hour week means he did not have overtime hours. Therefore the solution is,

5.50(44.5) = 244.75 Dollars.

It’s 24.6 after you round to the nearest tenths the answer should be 25.0

Understanding what? lol
