Question
The given equations model the number of teachers and students in a high school from 2002 through 2017. In the equations, n is the number of years after 2002 , where n is a whole number less than or equal to 15. The predicted number of teachers and students are T (n) and, respectively.
Based on the model, how many teachers are predicted to be in the high school in 2017?
- 80
- 90
- 95
- 100
The correct answer is: 95
The predicted number of teachers and students are T(n) = 80 + n
where n is the no. of years after 2002.
Here, n = 2017 - 2002 = 15.
T(15) = 80 + 15 = 95.
∴predicted no. of teachers in high school in 2017 is 95.
