Algebra 1 Word Problems



During the period 1985-2012, the projected enrollment B (in thousands of students) in public schools and the projected enrollment R in (in thousands of students) in private schools can be modeled by
B = -18.53t^2 + 975.8t + 48,140
and
R = 80.8t + 8,049

where t is the number of years.

A: Write an equation that models the difference in the projected enrollments for public schools and private schools as a function of the number of years since 1985

B: Find the difference in projected enrollments for public schools and private schools in 2005.
