The number of customers visiting a local movie theater since the year 2000
can be modeled by the expression
-3x2 - 27x + 825, where x is the
number of years since 2000. What
is the quotient if you divide the
expression by -3?
A x2 - 9x + 275
B x2 + 9x - 275
C x2 - 9x - 275
D-X2 - 9x + 275

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.
