In September 2017, Cullumber Corp. commits to selling 162 of its iPhone-compatible docking stations to Better Buy Co. for $14,904 ($92 per product). The stations are delivered to Better Buy over the next 6 months. After 90 stations are delivered, the contract is modified and Cullumber promises to deliver an additional 42 products for an additional $3,654 ($87 per station). All sales are cash on delivery.

Prepare the journal entry for Cullumber for the sale of the first 90 stations. The cost of each station is $53. Prepare the journal entry for the sale of 10 more stations after the contract modification, assuming that the price for the additional stations reflects the standalone selling price at the time of the contract modification. In addition, the additional stations are distinct from the original products as Cullumber regularly sells the products separately.

Prepare the journal entry for the sale of 10 more stations (as in (b)), assuming that the pricing for the additional products does not reflect the standalone selling price of the additional products and the prospective method is used.
