Answer:
Ted's annual salary is $10200
Explanation:
It is assumed that each month has 4 weeks and one year has 12 months.
If one multiplies the total months in a year by the weeks that each month has, the total of weeks in a year is obtained.

Weeks in a year

It means that one year has 48 weeks.
Weeks in six months
Now, the problem says that Ted Freeman just works six months of the 12 months that a year has. So, the previous procedure is repeated but with 6 months in a year.

The obtained result means that Ted Freeman works just 24 weeks in the entire year.
Salary

So, Ted's annual salary is $10200
