Answer:
1960hours
Step-by-step explanation:
There are 52weeks in 12 months and the electrician is suppose to work 40hours each week. i.e
40hours x 52weeks = 2080hours
If the plan is to give the electrician a three weeks vacation as benefit, it means the electrician will not be working for
40hours x 3weeks = 120hours
Therefore the number of hours that the electrician will work for 12months will be equal to 2080 hours - 120hours = 1960hours
