Answer provided by our tutors
the editor gets a fixed raise of $2,110 a year
after t = 8 year she is making f(8) = $51,700
let x be the salary before the first raise
f(0) = x
f(t) = x + t*2110
51700 = x + 8*2110
x = 51700 - 8*2110
x = 34,820
f(t) = 34,820 + 2110t is the formula for the income where t are the years she worked.
