(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 300-gal capacity tank contains a solution of 200 gals of water and 50 lbs of salt. A solution containing 3 lbs of salt per gallon is allowed to flow into the tank at the rate of 4gal/min. The mixture flows from the tank at the rate of 4 gal/min. The mixture flows from the tank at the rate of 2 gal/min. How many pound of salt are in the tank at the end of 30 min? When does the tank start to overflow? How much salt is in the tank at the end of 60 min?

2. Relevant equations

[tex] \frac{dx}{dt} + \frac{F}{V_o}x = F_i C_i [/tex]

3. The attempt at a solution

I really don't know how to start the equation, i mean i don't know where to substitute the values on the right variable. So I just need help on where to assign the values given.
