<font face="Times New Roman" size="+2">


(a) Write


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ C(b)\ =\ \frac{2}{5}(b)^2\ -\ 24(b)\ +\ 600]


in pencil.  Then erase every instance of a *[tex \Large b] and replace it with the number 20.  Then do the indicated arithmetic.


(b) Write


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ C(b)\ =\ \frac{2}{5}(b)^2\ -\ 24(b)\ +\ 600]


in pencil. Then erase *[tex \Large C(b)] and replace it with 3500.  Solve the resulting quadratic equation for *[tex \Large b].  Discard the negative root and round the positive root DOWN to the next lower integer.
