Mae Assurian is an electrician. She works from 6:45 a.m. to 3:30 p.m. Monday through Friday, and takes a 45-minute break for lunch. How many hours per week does Mae work?

6:45 am - 2:45 pm = 8 hours

2:45 -3:30 pm = 45 minutes (which you can ignore since he takes 45 minutes for lunch each day)

8 x 5 + ??

40

To calculate the number of hours Mae works per week, we need to subtract the time spent on break from the total working hours. Let's break it down:

Mae works from 6:45 a.m. to 3:30 p.m., which implies she works for 8 hours and 45 minutes each day (from 6:45 a.m. to 3:30 p.m. represents a time span of 8 hours and 45 minutes).

To find the total working hours for the week, we multiply the daily working hours (8 hours and 45 minutes) by the number of working days (5 days in a week, Monday through Friday).

8 hours and 45 minutes can be written as 8.75 hours (45 minutes divided by 60 minutes).

So, the calculation would be:
Total working hours per week = (8.75 hours/day) x (5 days/week)

Multiplying these values:
Total working hours per week = 43.75 hours

Therefore, Mae works for approximately 43.75 hours per week.
