Answer:
45%
Step-by-step explanation:
For simplicity, let use assume there are 100 students in the school.
No. of students to complete college = (30/100) x 100 = 30 Students
President wants to increase by 50% = (50/100) x 30 = 15 Students

Total number of students = 100 students
Therefore;
Rate goal % = (45/100) x 100% = 45%
D) initial value of 60 and multiplying by 1/3
