A professor gives two types of quizzes, objective and recall. He is planning to give at least 15 quizzes this quarter. The student preparation time for an objective quiz is 15 minutes and for a
recall quiz 30 minutes. The professor would like a student to spend at least 5 hours (300 minutes)
preparing for these quizzes above and beyond the normal study time. The average score on an
objective quiz is 7, and on a recall type 5, and the professor would like the students to score at
least 85 points on all quizzes. It takes the professor one minute to grade an objective quiz, and 1.5
minutes to grade a recall type quiz. How many of each type should he give in order to minimize
his grading time?
