Therefore, 144 quarters are required until the account balance is $0

Explanation:

Present Value=Quarterly payment * (1 - ((1+r) ^ (-n)) / n

$3,00,000 = $4500 * (1 - ((1+0.0125) ^ (-n)) / 0.0125

$3,00,000 = $360000 * (1 - ((1+0.0125) ^ (-n))

(1 - ((1.0125) ^ (-n)) = $300000 / $360000

(1 - ((1.0125) ^ (-n)) = 0.833333

n = 144
