Joesphine scored 95, 84, and 87 on three math tests. She wants her average score for 5 tests to be at least 90.

Part A: What are two possible test grades she could get to reach her goal? Justify your reasoning.
Part B: What are the two lowest grades she could get and still get at least a 90 average? Prove your result.
I am very confused. Please help...
