an editor gets a 2110 raise each year. after 8 years she makes 51,700 per year. write an equation that gives her income as a function of how many years she has worked
starting at P, her pay after y years is
p(y) = P+2110y
We know that p(8) 51700, so
P+2110*8 = 51700
P = 51700-16880
P = 34820
So, the final equation is
p(y) = 34820 + 2110y
