Khan Computer Corporation sold software to a customer for $217,000. As part of the contract, Khan promises to provide "free" technical support over the next six months. Khan sells the same software without technical support for $189,000 and a stand-alone six-month technical support contract for $81,000, so these products would sell for $270,000 if sold separately. Required: Prepare Khan's journal entry to record the sale of the software. Note: If no entry is required for a transaction/event, select "No journal entry required" in the first account field
