Answer:
14.27%
Step-by-step explanation:
First,
Net income = Sales revenue - Fixed cost
Where
Sales revenue = Number of students × TI charges per students
= 1,300 students × $360
= $468,000
Hence,
Net income = $468,000 - $140,000 = $328,000
For the second case
Net income = Sales revenue - Fixed cost
Where
Sales revenue = Number of students × TI per students
= 1,430 students × $360
= $514,800
Net income = $514,800 - $140,000 = $374,800
The percentage increase
= ($374,800 - $328,000) ÷ $328,000
= 14.27%
