A student's grade in a course is the average of 4 test grades and a final exam that is worth four times as much as each test. Suppose a student has test grades of 89, 90, 75, and 90. Write an equation to model this situation where x is the student's grade on the final exam and y is the student's average for the course.
Then find the score they will need to receive on their final exam if they want to have a grade of 88 for the course.
Final exam score needed=___________________ =
