Ross receives a $24,750 per year scholarship from University of Hawaii. The University specifies that $19,500 is for tuition, books, supplies, and equipment required for classes. The remaining portion is for room and board. As part of the condition of the scholarship, Ross must also work twelve hours per week as a grader, for which he is paid $10,500 for the year.

Of the total amount received, how much, if any, must Ross include in taxable income?
