Hi Tyler,
One thing you can do is go back and watch the video at the end of Unit 3 about the loose connection. It is also a 240vac circuit with two “loads” in series (even if one of the loads is accidental, from the loose connection.) It is similar to Question 7 in the Voltage Drop quiz.
The basic technique is to calculate the circuit current (and to remember that the current is the same throughout a series circuit), then knowing that you can calculate either voltage drop or power across each individual load.
Let me know if that helps, or if you have any more specific questions about what I wrote above.
