Answer:
$61,071.36
Explanation:
According to the scenario, computation of the given data are as follows,
Value of note = $640,000
So, Carrying value of note on Jan 1, 2020 = $640,000 × 0.71
= $454,400
Prevailing interest rate = 12%
So, Interest for 2020 = $454,400 × 12% = $54,528
Now, Interest revenue for 2021 = ($454,400 + $54,528) × 12%
= $508,928 × 12%
= $61,071.36
Hence, the amount of interest revenue that should be included in Swifty's 2021 income statement is $61,071.36
