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: 

![\int d[C(40+2t)]=\int(120+6t)dt\\C(40+2t)=120t+3t^2+k_0\\C(t)=\frac{120t+3t^2}{40+2t}+\frac{k_0}{40+2t}](https://tex.z-dn.net/?f=%5Cint%20d%5BC%2840%2B2t%29%5D%3D%5Cint%28120%2B6t%29dt%5C%5CC%2840%2B2t%29%3D120t%2B3t%5E2%2Bk_0%5C%5CC%28t%29%3D%5Cfrac%7B120t%2B3t%5E2%7D%7B40%2B2t%7D%2B%5Cfrac%7Bk_0%7D%7B40%2B2t%7D)
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
Y/5-10 is the answer
Put it as a fraction. Y would be the numerator and the 5-10 as the denominator
