200 = P e^20k 1000 = P e ^ 30k ln 200 = ln P + 20k ln e ln 1000 = ln P + 30k ln e ln 200 = ln P + 20k ln 1000 = ln P + 30k ln 1000 - ln 200 = 10k ln 1000 - ln 200 = ln (1000/200) = ln 5 (ln 5) / 10 = k 200 = P e^ 20(ln 5) / 10 200 = P e^ 2(ln 5) 200 ÷ e^ 2(ln 5) = P e^ 2 ln 5 = e^ ln 5^2 = e ^ ln 25 = 25 200 = p(25) 8 = P then go from there
