Problem 12-22 Simple circuit

In the figure, what are
(a) the current through the $47\; \Omega$ resistor?
(b) the direction of the current through the $47\; \Omega$ resistor?
(c) the potential difference $V_A - V_B$?  $V_B - V_A$?
(d) the voltage across the $84\; \Omega$  resistor?
(e) the potential at point $C$, if we define the potential at the negative terminal of the battery to be zero?

What is the reduced circuit diagram for this case?

(A)
