Julie wants to have a 90 average in her math class at the end of the year. She is trying to determine what she needs to make on
her final exam for this to work. Everything is weighted equally and she currently has a 85 for her quiz average, a 80 for her homework average, a 92 for her test average, and a 98 for her project average. What does she need to make on her final exam for her to end up with a 90 in the class?
