How do I write this problem?
to receive a grade B- in a math course, you must have a mean of 83 on five tests (4 tests + one final) all 100 pts maximum each. Your scores thus far are 85,79,82,and 81. How many points must you have on the final, to earn the B-? write down your work..
0.83 * 500 = 415
You need a total of 415 points.
Your test grades so far = 327
415 = 327 = 88
You need at least a score of 88 on the final.
thank you ms. Sue.. the four scores threw me off and wasn't sure how to start the formula or problem
I just noticed that I have a typo:
415 - 327 = 88
thank you you are a life saver
