The enrollment of a school was 1200. Since then, it has increased at a rate of 35 students per year. Write an equation to repres
Romashka [77]

The general equation to represent the enrollment of the school each year after 2000  = 1200 +35 n    

where n = number of years after 2000.

Step-by-step explanation:

Here, according to the question:

The initial number of students enrolled in the school = 1200 students

The number of students increased each year  = 35 students

Now if the initial year is 2000, then the number of student in the first year

= Initial enrollment  +  ( n  x Number of students increasing each year )

where n : The total number of years after 2000

So, the number of students in first year after 2000 for n = 1 is

1200 + ( 1 x 35)  = 1235

The number of students in second year after 2000 for n = 2  is

1200 + ( 2 x 35)  = 1270

The number of students in third year after 2000 for n = 3 is

1200 + ( 3 x 35)  = 1305

Hence, the general equation to represent the enrollment of the school each year after 2000  = 1200 +35 n    where n = number of years after 2000.
