Answer: the answer is that you will have $3630 in the account at the beginning of the 7th year.
Explanation:
I = Prt
Using this formula:
I = Prt
I = 3000 x 0.035 x 6
I = $630
Therefore, the total amount in the account at the beginning of the 7th year will be
Total = Principal + Interest
Total = $3000 + $630
Total = $3630
