Question: Pure water is running into a brine solution, and the same amount of solution is running out. The number n of kilograms of salt in

Pure water is running into a brine solution, and the same amount of solution is running out. The number n of kilograms of salt in the solution after t min is found by solving the equation ln n = −0.04t + ln 20. Solve for n as a function of t.
