Answer:
L. 35-x
Step-by-step explanation:
The questions says "this was x dollars more than you earned thursday" So in this situation we are trying to find how much exactly more did you earn or how much was thursday's earning.
Therefore 35-x works because since you made 35 Saturday which is the higher amount than what you made on Thursday as indicated by question.
what you made of saturday-how much more it was compared to thursday= gives you what you made thursday!
