To find the electrician's earnings for half a year, we will perform a series of multiplications. Here are the steps:
1. Determine the number of hours the electrician worked in a week.
2. Determine the number of weeks in half a year.
3. Determine the electrician's hourly wage.
4. Multiply the number of hours per week by the number of weeks in half a year to find the total hours worked in half a year.
5. Multiply the total hours worked by the hourly wage to find the total earnings for half a year.
Now, let's apply these steps:
1. The number of hours the electrician worked in a week is given as 28 hours.
2. Half a year is half of 52 weeks, so it would be 26 weeks (since 52 ÷ 2 = 26).
3. The hourly wage given is $25.
4. To find the total hours worked in half a year, we multiply the hours per week by the number of weeks:
Total hours worked = 28 hours/week × 26 weeks = 728 hours
5. To calculate the total earnings, we multiply the total hours worked by the hourly wage:
Total earnings = 728 hours × $25/hour = $18,200
Therefore, the correct answer is $18,200, which seems to be represented by option 'C. $1,8,200' despite the typo. The correct formatting of the answer should be $18,200.
