Question 410536
3 years ago they have 6000 subscribers
the number of subscribers increases by 69 each month.


let n = number of months the paper has been printed.


formula would be:


B = 6000 + 69*n


when n = 0, B = 6000
when n = 1, B = 6000 + 69*1`
when n = 2, B = 6000 + 69*2
etc.


after 3 years, the number of subscribers becomes:


6000 + 69*36 = 6000 + 2484 which equals 8484.
