22. The information provided is the number of minutes worked for each weekday for two weeks.
23. Up to this point, no problem is stated. If we read ahead to question 24, the problem is to determine if the number of hours worked in a week exceeds 40. The steps to solve the problem are ...
... a) convert the times to compatible units (minutes to hours or hours to minutes)
... b) compare the total time worked in a week to 40 hours (or the equivalent), or compare the time worked each day to 8 hours.
... c) on the basis of the comparison(s) in (b), decide if overtime was worked.
24. 8 hours is (60 min/h)×(8 h) = 480 min.
Only 5 days were worked each week, and no day exceeded 8 hours (480 min), so the total time is less than 40 hours. Mary does NOT need to pay overtime.
