and the total of 10,000g of chemical is evenly dissolved in the water

Fresh water starts pouring into the pond at the rate of 300 gallons/hour and the pond also releases water at the rate of 300 gallons/hour (hence no change in total amount in the pond).

Can you set up a differential equation describing the rate of change of the chemical in the pond. (dc/dt)

(I know that dC/dt = (the total amount of the chemical in the pond at a given time / 1,000,000 gallons of waer)*300 gallons/3600seconds) but i cant define the total amount of chemcial left in the pond at a given time, as the total amount doesnt change linearly or by a pattern i can see )
