Calculate my grade and what I need to get in order to have the possibility of passing the class with a C. Midterm 1 and 2are 25% each. Final is 30%

HW/Quiz are 20%. Total is 100%

So far my first test I got a 74.89 and second I got a 57.90. My hw I got a 1.4 and quiz a 0.5. We will get two more homeworks (and thats it) each valued at at 2 points each. Grading scale is 90%A, 80%B, 70%C, 60%D. So what do I need to get to pass with a C?
