Potential Energy Change in an RC Circuit

Question

An RC circuit consists of a 20 V battery, a 5 μF capacitor, and a 2 MΩ resistor. At the instant the capacitor is charged to 75% of its maximum value, what is the total change in electric potential energy for the charge that has passed through the resistor?
