A 500 liter tank originally contains 300 liters of liquid in which there's dissolved 50 grams of some chemical. Liquid containing 30 grams per liter of the dissolved chemical flows into the tank at the rate of 4 liters/min. The mixture is uniform and it flows out at a rate of 2 liters/min. How much of the chem is inside at the time it overflows?
Here's my work:
There is 300+2t liters of liquid in the tank. I'm going to simplify liters with L.
Use initial condition .
Determining the time of overflow:
Sub in for t.
