Option b) 1960 is the total hours worked by the electrician.
Step-by-step explanation:
It is stated that a full-time electrician will put in 40 hours weekly.
Hence, we should determine the total hours he could work in a year, which consists of twelve months.
Thus, a year consists of 365 days.
To find the number of weeks in these twelve months:
Number of weeks = Total days in a year / 7 days of the week
⇒ 365 / 7
⇒ 52.14 (approximately 52 weeks)
It translates to 52 weeks within twelve months.
Out of these 52 weeks, three weeks are designated for vacation.
The total weeks the electrician will work = 52 weeks - 3 weeks
⇒ 49 weeks.
Thus, the electrician worked for 49 weeks.
To find his total worked hours = 49 weeks × 40 hours
⇒ 1960 hours.
So, the total hours the electrician worked amounts to 1960 hours, which corresponds to option b).
