Answer:
On July 1, 2017, Waterway enters into a contract with a customer for the purchase and installation of window for a price of $2,400.
Hence, there is no journal entry.
On September 1,2015.
Total = Windows + Installation
= $2,040 + $630
= $2,670
Revenue recognized:
= Installation + Windows
= [($630 ÷ $2,670) × $2,440] + [($2,040 ÷ $2,670) × $2,440]
= (0.2359 × $2,440) + (0.7640 × $2,440)
= $576 + $1,864
= $2,440
Therefore, the journal entries are as follows:
On September 1,
(i)
Cash A/c Dr. $2,040
Account receivable A/c Dr. $400
To unearned service revenue $576
To sales revenue $1,864
(ii) Cost of goods sold A/c Dr. $1,130
To Inventory A/c $1,130
On 15 October,
Cash A/c Dr. $400
Unearned service revenue A/c Dr. $576
To Service revenue (installation) $576
To Accounts receivable $400
(Revenue recognized after service provided)
