Answer:
The employer´s address.
Explanation:
The inside address on a business letter is the receiver´s address. It is the same information that is put on the outside address on the envelope to help the Postal Service to know where to deliver it.
Then, when the envelope is off, at the beginning of the letter itself goes the inside address. This is to know from whom the letter is after the letter is open.
I hope this answer helps you.
