Answer:
76.09 pounds
Step-by-step explanation:
From the information given:
At a slower of 4 gal/min, the solution gets pumped out;
So,
The differential of the equation is:
For the linear differential equation, the integrating factor is determined as:
Multiplying with the above integration factor;
By using the given condition:
A(0) = 40
40 = 50 + c (50)⁻²
10 = c(50)⁻²
OR
c = -10 × 2500
c = -25000
A = (50 + t) - 25000(50 + t)⁻²
The number of pounds of salt in the tank after 30 min is:
A(30) = (50+30) - 25000(50 + 30)⁻²
Thus, the number of pounds of salt in the tank after 30 min is 76.09 pounds.
