3. The number of teachers at a local high school that have entered final exam scores at time f hours from 8AM is modeled by the function F. the solution to a logistic differential equation. At 8AM, only 3 of the 80 teachers have entered their final exam scores. Also, at SAM. F is increasing at a rate of 6 teachers per hour. Which of the following could be the logistic differential equation? (A) aF de F (80 - F) dF B di 231 F(80 - F) (C) dF de 148 F(80 - F) AF (D F(80 - F)
