Answer:
96.46
Step-by-step explanation:
Volume of the Gallon =140 gallons
At time t=0, V(0)=40 gallons
V(t)=2t+k, Where K is a constant.
Since V(0)=40
V(0)=2(0)+k=40
k=40
V(t)=40+2t
The Change in Salt Concentration
Rearranging
Using Integrating Factor:
At t=0, C(0)=0.125, k_0=5
At V(t)=140
V(t)=40+2t=140
t=50
Just the tank overflows, C(t)=96.46
