a. years since 1990 (t) = 30
enrollment: n = -0.3|30 - 8|+11 = -0.3*22 + 11 = 4.4, which means 4400 students
b. Replacing into the equation with n = 10, we get:
10 = -0.3|t - 8|+11
10 - 11 = -0.3|t - 8|
(-1)/(-0.3) = |t - 8|
10/3 = |t - 8|
t - 8 = 10/3 or t - 8 = -10/3
t = 10/3 + 8 t = -10/3 + 8
t = 11 1/3 t = 4 2/3
t = 11 1/3 corresponds to year 1990 + 11 = 2001
t = 4 2/3 corresponds to year 1990 + 4 = 1994
