Find the equilibrium values for B and F .
Chemicals enter a house’s basement air. Let F (t ) and B(t ) be the amount of chemical (in mg m3 ) in the first floor air and the basement air after t minutes, respectively. Let’s suppose that the rate of change of F and B are given by the equations: B'= -0.018B + 0.72 and F' = 0.015B - 0.036F. What will be an ideal response?
