**Problem Statement for Educational Use:** A 90-gallon tank initially contains 10 gallons of water and 5 pounds of salt. Salt solution, at 2.5 lb/gal, begins entering the tank at a rate of 4 gal/min. Simultaneously, a 3 gal/min drain is opened in the bottom of the tank. Let \( s(t) \) be the amount of salt in the tank at time \( t \). Find the differential equation and initial condition for which \( s(t) \) is a solution. **DO NOT SOLVE THE DIFFERENTIAL EQUATION.**
