When a new charter school opened in 2005, there were 350 students enrolled. Since then, the student population has decreased by 100 students every two years. Choose the formula below which gives the function N(t) representing the number of students attending the charter school t years after 2005.

Select the correct answer below:

N(t)=100t+350

N(t)=−100t+350

N(t)=50t+350

N(t)=−50t+350

N(t)=350t+100

N(t)=−350t+100
