Given:
$300 per month in 12 years.
1 year = 12 months = 300 x 12 = $3600
For 12 years = $3600 x 12 = $43 200
Principal (P) = $43 200
rate(r) = 3.05% = 0.0305
Time (t) =12
n = 12
Using the formula below:
Substitute into the formula and evaluate
Therefore, the account balance at the end of the 12 years is $62263.55
