Ryan is a BYU-I student taking an advanced math class in which exams are worth 70%, homework is worth 20%, and quizzes are worth 10%. His exam scores average to 89.5%, homework averages 94.1%, and his quiz average is 85%.
What is his overall percentage (to the nearest 100th) in the class thus far, and what must his test average increase (to the nearest 10th) to in order to qualify for an A in the class?
(Note: an overall score of 93.5%, or higher, would mean an A for this particular math course Ryan is taking.)
