Answer: Warranty liability account in the amount of $200.
Step-by-step explanation:
The estimated warranty as it relates to a particular month are debited to the income statement and a corresponding credit entry is made to the liability accounts even though no claim has been made nor payment.
However when the claims are made and payment is to be effected, the bank account is credited and the liability is debited to reduce the liability.
If the warranty claim is higher in the long run than the estimation made the income accounts is further debited with the increment and if it's lower the income account is credited with the amount.
