Kayla has a 41% grade average. On an exam that is worth 20% of her grade she gets a 100%. What is her grade now?

asked by Ashley
  1. The 41% she has now is 80% of her final grade, so
    she already has 41(.8) or 32.8 %
    For her final she get all of the available 20%

    final grade = 32.8+20 or 52.8% probably rounded to 53 %
