Answer 1

all parts has been answered

Explanation:

Let us assume

after T years both colleges have same enrollment

Enrollment at college A after T years = 18400+500*T

Enrollment at college B after T years = 37650-1250*T

Both the colleges will have same enrollment after T years

Hence

18400+500*T=37650-1250*T

1750*T=19250

T=11 years

Present year would be =2005+11=2016

In the year 2016, the enrollment of both the colleges will be same.

Total enrollment at each college = 18400+11*500=37650-1250*11=23900

The total enrollment at each college will be 23900 students
