Problema Solution
Mary is calculating how many hours of overtime she has worked for one week. She worked two and a half hours overtime on Friday, three and three quarter hours on Saturday, and two thirds of an hour on Sunday. How many hours of overtimes did she work? If she gets paid $45 per hour for overtime, how much extra income did she make?
Answer provided by our tutors
two and a half hours overtime on Friday = 5/2 hours
three and three quarter hours on Saturday = 15/4 hours
two thirds of an hour on Sunday = 2/3 hours
Total amount of overtime = 5/2 + 15/4 + 2/3 = 83/12 hours
extra income = 45 * 83/12 = 1245/4 =311.25 dollars
