b The number of liters of blood pumped through the lungs in one minute is given by C = , where b is quantity of a - v oxygen used by the body in one minute, a is the quantity of oxygen per liter of blood that has just gone through the lungs, and v is the quantity of oxygen per liter of blood that is about to enter the lungs. Suppose a = 160, b = 195, and v = 125. Estimate the change in C if a becomes 145, b becomes 190, and v changes to 125. (E Find the equation for the total differential of C to estimate the change in C. (10 = Dds + |:|db + |:|dv
