Answer:
25000
Step-by-step explanation:
Let enrollment be represented by E.
E(1999) = [tex]\frac{10}{100}*E(1998) +E(1998)[/tex]
E(1999)=1.1E(1998) ............................equation 1
E(2000)= 0.08E(1999)+E(1999)
E(2000)=1.08E(1999)
enrollment in 2000, E(2000) is 29700.
29700 = 1.08E(1999)
E(1999) =29700/1.08
E(1999) =27500
from equation 1;
E(1999)=1.1E(1998)
27500 = 1.1E(1998)
E(1998) =27500/1.1
E(1998) = 25000
Enrollment in 1998 = 25000
