Let’s suppose 2.5 mg of glactosyl human serum (Tc-GSA) is injected into the bloodstream. Let B and L be the amount of Tc-GSA in the blood and liver, respectively. The quantities B and L are related by:
4 = B + L
dB / dt = -0.06B + 0.03L and
dL /dt = 0.06B - 0.03L
At equilibrium, the quantities B and L are constant. Find
the equilibrium amount of Tc-GSA in the blood and liver.
B = 4/3 mg, F = 8/3 mg

Solve the problem.Mary, the owner of Vitallo's Pizza Parlor, had start-up costs of $5700. The ingredients for each pizza cost $3.25, and she sells each pizza for $11. She has no other expenses. Express the cost C as a function of x, where x represents the number of pizzas sold.
A. C(x) = 3.25x + 11 B. C(x) = 3.25x + 5700 C. C(x) = 3.25x + 5711 D. C(x) = 5700x + 3.25
