Linear Equations
When a new charter school opened in 2000, there were 540 students enrolled. Write a formula for the equation N, representing the number of students attending this charter school t years after 2000, assuming that the student population:
Increased by 28 students per year	N=
Decreased by 40 students per year	N=
Increased by 48 students every 2 years	N=
Decreased by 36 students every 4 years	N=
Remained constant (did not change)	N=
Increased by 10 students every semester (twice each year)	N=
