Explanation Given Information: The rate of change in sales S (in thousands of units) of a product is proportional to the difference between L and S at a time t (in the year) where L is the estimated maximum level of sales (in thousands of units). Also, the given condition is S = 0 if t = 0 . Formula used: Step 1: Find the differential equation using the given condition. Step 2: Solve that differential equation and find the value of integrating constant using initial condition. Step3: Substituting the given value in the equation and find the required differential equation. Calculation: Consider the provided condition, d S d t ∝ L − S So, d S d t = k ( L − S ) where k is the proportional constant. Rewrite the expression d S d t = k ( L − S ) as, d s L − S = k d t Integrating the above equation both sides, − ln ( L − S ) = k t + c Initially, when t = 0 then S = 0 . Substitute the equation in the equation − ln ( L − S ) = k t + c . − ln ( L − S ) = k t + c − ln ( L − 0 ) = k × 0 + c c = − ln L putting the value of c in the general solution − ln ( L − S ) = k t + c
