Math

Sarah was trying to figure out her grades for her math course. She only knew the grade of 4 of the tests she had taken, however the class had taken 5 tests total. She scored a 94, 67, 83, and 93. If Sarah ended up with a grade of 90, what did she get on the 5th and final test?

94 + 67 + 83 + 93 = 337
337/4 = 84
Where am I going wrong?

  1. 0
  2. 9
asked by Bella
  1. 337 is her total score, and 84.25 is her current average up to the fourth test.

    If she ended up with a grade of 90, that means her total score (for all five tests) is 5*90=450.

    So what did she score in the final test?
