Answer:
Louis $61.43 now.

Louis sells her bike and helmet for $88.50 and $8.75. Add these together and it gives you the total amount of money she has earned. 

Louis now has $97.25. She then buys something for $35.82, so, subtract the amount of the basketball by the amount of money she earned to find out how much money she has left. 

Louis now has $61.43.
