Answer:
37%
Explanation:
The computation is shown below:
In the first case,
The net income is
= Sales revenue - fixed cost
where,
Sales revenue = Number of students × TI charges per student
= 750 students × $250
= $187,500
So, the net income is
= $187,500 - $85,000
= $102,500
Now on the second case
The net income is
= Sales revenue - fixed cost
where,
Sales revenue = Number of students × TI charges per student
= 900 students × $250
= $225,000
So, the net income is
= $225,000 - $85,000
= $140,000
So, the percentage increase is
= ($140,000 - $102,500) ÷ ($102,500)
= 37%
