My last problem and I'm stuck please help!!​

The classrooms are trying to raise $1,200.00 for charity. mrs. leblanc's class has raised 50%. mr. patel's class has raised $235.14 ms. warner's class has raised 1/3 as much as mrs. leblanc's class. how much more money is needed to reach the goal of $1,200.00?

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?
