After the first year, the ratio of change in time to change in profit is constant. Let x be years and P be profit in dollars.

After the first year, the ratio of change in time to change in profit is constant:
over three years, the profit grows from 28700 to 74000:
(74000-28700)/3 = 15100
the profit growth per year is then $15,100
P(x) = 15100x + 28700
