Answer and Explanation:
It has been given that Marc receives a scholarship of $6,000 out of which he pays a tuition fee of $2,400 and $3600 for his room rent and board expenses.
The value of the tuition fee will be deducted and $3,600 will be considered as Marc's gross income.
Gross income for Marc = $6,000 - $2,400
Gross income for Marc = $3,600
