The rate of change in sales S is inversely proportional to time t (t > 1) measured in weeks. Find S as a function of t if sales after 2 and 4 weeks are 250 units and 400 units respectively. S(t) = 50[3lnt ln2 + 2] S(t) = 650[lnt ln150 + 50] S(t) = 50[3lnt ln2 + 13] S(t) = 50[13lnt ln2 + 2] S(t) = 650[lnt ln150 + 1]
