Let S(t) denote the amount of sugar in the tank at time t. Sugar flows in at a rate of
(0.04 kg/L) * (2 L/min) = 0.08 kg/min = 8/100 kg/min
and flows out at a rate of
(S(t)/1600 kg/L) * (2 L/min) = S(t)/800 kg/min
Then the net flow rate is governed by the differential equation
![\dfrac{\mathrm dS(t)}{\mathrm dt}=\dfrac8{100}-\dfrac{S(t)}{800}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20dS%28t%29%7D%7B%5Cmathrm%20dt%7D%3D%5Cdfrac8%7B100%7D-%5Cdfrac%7BS%28t%29%7D%7B800%7D)
Solve for S(t):
![\dfrac{\mathrm dS(t)}{\mathrm dt}+\dfrac{S(t)}{800}=\dfrac8{100}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20dS%28t%29%7D%7B%5Cmathrm%20dt%7D%2B%5Cdfrac%7BS%28t%29%7D%7B800%7D%3D%5Cdfrac8%7B100%7D)
![e^{t/800}\dfrac{\mathrm dS(t)}{\mathrm dt}+\dfrac{e^{t/800}}{800}S(t)=\dfrac8{100}e^{t/800}](https://tex.z-dn.net/?f=e%5E%7Bt%2F800%7D%5Cdfrac%7B%5Cmathrm%20dS%28t%29%7D%7B%5Cmathrm%20dt%7D%2B%5Cdfrac%7Be%5E%7Bt%2F800%7D%7D%7B800%7DS%28t%29%3D%5Cdfrac8%7B100%7De%5E%7Bt%2F800%7D)
The left side is the derivative of a product:
![\dfrac{\mathrm d}{\mathrm dt}\left[e^{t/800}S(t)\right]=\dfrac8{100}e^{t/800}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dt%7D%5Cleft%5Be%5E%7Bt%2F800%7DS%28t%29%5Cright%5D%3D%5Cdfrac8%7B100%7De%5E%7Bt%2F800%7D)
Integrate both sides:
![e^{t/800}S(t)=\displaystyle\frac8{100}\int e^{t/800}\,\mathrm dt](https://tex.z-dn.net/?f=e%5E%7Bt%2F800%7DS%28t%29%3D%5Cdisplaystyle%5Cfrac8%7B100%7D%5Cint%20e%5E%7Bt%2F800%7D%5C%2C%5Cmathrm%20dt)
![e^{t/800}S(t)=64e^{t/800}+C](https://tex.z-dn.net/?f=e%5E%7Bt%2F800%7DS%28t%29%3D64e%5E%7Bt%2F800%7D%2BC)
![S(t)=64+Ce^{-t/800}](https://tex.z-dn.net/?f=S%28t%29%3D64%2BCe%5E%7B-t%2F800%7D)
There's no sugar in the water at the start, so (a) S(0) = 0, which gives
![0=64+C\impleis C=-64](https://tex.z-dn.net/?f=0%3D64%2BC%5Cimpleis%20C%3D-64)
and so (b) the amount of sugar in the tank at time t is
![S(t)=64\left(1-e^{-t/800}\right)](https://tex.z-dn.net/?f=S%28t%29%3D64%5Cleft%281-e%5E%7B-t%2F800%7D%5Cright%29)
As
, the exponential term vanishes and (c) the tank will eventually contain 64 kg of sugar.
Your method is right so u already know how to do it
