A professor announces that course grades will be computed by taking 40% of a student’s project score (0–100 points) and adding 60% of the student’s final exam score (0–100 points). If a student gets an 86 on the project, what score can she get on the final exam to get a course grade of at least 90? Write an inequality that describes the student's situation. Let f represent the final exam.
