Answer:
$27,540
Step-by-step explanation:
Expected amount = Possible amount into probability
Expected amount = ($54,000*80%) + ($54,000+10%)*20%
Expected amount = $43,200 + ($54,000+$5,400)*20%
Expected amount = $43,200 + $59,400*20%
Expected amount = $43,200 + $11,880
Expected amount = $55,080
Revenue to be recognized on this contract in 2021 = $55,080 * 6/12 = $27,540.
