2.69 Determine the total resistance, R7, in the circuit in Fig. P2.69.

Have a good idea on how to do the first part in that I found the resistance than used this with the known voltage to calculate the power. Unsure on part b however in that I don't know how to calculate the cities resistance to compare it to the total power output to it.
