Transcribed Image Text:Fresh water flows into tank 1; mixed brine flows from tank 1 into tank 2, from tank 2 into tank 3, and out of tank 3; all at
the given flow rater gallons per minute. The initial amounts x₁(0)=xo (lb), and x₂(0) = 0, and x3 (0) = 0 of salt in the
three tanks are given, as are their volumes V₁, V₂, and V3. First solve for the amounts of salt in the three tanks at
time t, then determine the maximal amount of salt that tank 3 ever contains. Finally, construct a figure showing the
graphs of x₁ (t), x₂ (t), and x3 (t).
r=60, x=60, V₁ = 15, V₂ = 12, V3 = 20
X₁ (t) =
X₂ (t) =
X3 (t)=
