Question

1 3. [2.3 3 A tank originally contains 100 gallons of fresh water. Then water containing lb of salt per gallon is poured into the tank at a rate of 2 gal/min and the mixture is allowed to leave at the same rate. After 10 min the process is stopped and fresh water is poured into the tank at a rate of 2 gal/min, with the mixture again leaving at the same rate. Find the amount of salt in the tank after an additional 10 minutes

Please show your work (and reasons!) clearly and explain it like you think I'm dumb. I have tried this problem 3 times by myself and gotten 3 different (wrong) answers! I need your help!

Thanks!
