Explanation:
Since Kingbird's selling price equals $1,940, which the customer pays in advance, this amount is taken as the sales revenue. Though the stand-alone price of installation is estimated to be $580, only $530 is recorded as revenue for installation because the $580 remains an estimate of a stand-alone item.
