Answer:
b. If the employer accepts Turner's counteroffer, Turner will recognize as gross income $55,000 per month [($480,000 + $180,000)/12].
Explanation:
Given that
Turner annual salary = $600,000
Counteroffer to received a monthly salary = $40,000 or $480,000 annually
And, $180,000 bonus in 5 years at the age of 65
So the benefit he will be getting would be after accepting the counter offer is
= ($480,000 + $180,000) ÷ 12 months
= $660,000 ÷ 12 months
= $55,000
