Answer:
she works 1837.5 hours per year.
Step-by-step explanation:
recall that a year consists of 52 weeks. then if she takes off 3 weeks during the year, she in fact works (52 - 3 = 49) weeks per year.
During each week she works 5 days and each day she works 7.5 hours.
therefore, the total number of hours she works per week is : 5 * 7.5 hours = 37.5 hours per week.
Now during 49 weeks she would be working 49 * 37.5 hours = 1837.5 hours
