94+67+83+93 = 337
5*90 = 450
Looks like she needed a 113 on the final test. I suspect a typo. Fix it and redo the 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?
How do I solve this problem?
