My friend has currently 62.4% and the final exam is worth 30%. She's wondering how much she should get on the exam to at least pass or boost it up. Please show the math :o

  • How to calculate marks to pass with the exam - ,

    final mark= .3*FExam+.7*62.4

    I am not certain what final mark she needs, but calculate FExam

    Fexam=finalmark/.3- 145.6

  • How to calculate marks to pass with the exam - ,

    well, you did not say what mark was pass so I will assume it is like 65

    Say we have 100 exams in the year
    we have taken 70 and the last one is really 30 together

    .624 * 70 + x * 30 = .65 * 100

    x = (65 -43.68)/30 = .71 or 71 %

    It does not matter if we pick 100. the ratio between taken and remaining must just be 70/30 and the sum on the right
