Differential equation A tank initially contains 10 gal of fresh water. At t= 0, a tap is opened, pouring a brine solution containing 1/2 lb of salt per gallon into the tank at a rate of 2 gal/min. In the meantime, the solution is mixed evenly as it is stirred well in the tank and then the mixture exits at the same rate (2gal/min). Find the amount and concentration of salt in the tank at any time t. Please dont skip any steps even on the integrals
