Geraths Windows manufactures and sells custom storm windows for three-season porches. Geraths also provides installation service for the windows. The installation process does not involve changes in the windows, so this service can be performed by other vendors. Geraths enters into the following contract on July 1, 2014, with a local homeowner. The customer purchases windows for a price of $2,400 and chooses Geraths to do the installation. Geraths charges the same price for the windows irrespective of whether it does the installation or not. The price of the installation service is estimated to have a fair value of $600. The customer pays Geraths $2,000 (which equals the fair value of the windows, which have a cost of $1,100) upon delivery and the remaining balance upon installation of the windows. The windows are delivered on September 1, 2014, Geraths completes installation on October 15, 2014, and the customer pays the balance due. Prepare the journal entries for Geraths in 2014.

Refer to the revenue arrangement in BE18-11. Repeat the requirements, assuming (a) Geraths estimates the standalone value of the installation based on an estimated cost of $400 plus a margin of 20% on cost, and (b) given uncertainty of finding skilled labor, Geraths is unable to develop a reliable estimate for the fair value of the installation. (Round amounts to nearest dollar.)

Please answer both questions showing work so I can follow.

Thanks!
