Answer:
The initial payment will be D. $704.17
Explanation:
Joseph has obtained a $169,000, 5/1 30-year ARM at 5%.
During the first 3 years, he has an option of paying interest only. So, it is simple interest.
Simple interest is given as :

here, p = 169000
r = 5%
t = 30
Putting values in formula:
= $253500
As this is interest for 30 years or 360 months. So, for initial interest we will divide the interest with 360.
≈ $704.17
Therefore, the initial payment will be $704.17
