Detailed Answer
(a) The equipment sale is accounted for using the installment
method. The gross profit percentage on the sale is
33 1/3% ($600,000 profit ÷ $1,800,000 selling price). Since
$300,000 of the sales price is collected in year 2, gross profit of
$100,000 is recognized (33 1/3% × $300,000). The total revenue
recognized is $250,000 ($100,000 gross profit + $150,000
interest revenue).
