Answer

Answer:

B. He added up his transactions incorrectly.

Explanation:

Step1: Calculate total check amounts

$67.25 + 36.80+15.00=$119.05$

Step2: Calculate net change from other activity

$650.45 - 15.00=$635.45$

Step3: Calculate expected closing balance

$900 - 119.05+635.45 = 1416.40$. Since the calculated closing - balance matches the given closing balance, the error is likely in transaction addition, not in other factors like uncashed checks, mislabeled payments, or unrecorded fees.
