Q. Hana takes two examinations. Her overall grade for the course will be the maximum of her scores on the two examinations. She decides to spend a total of 400 minutes studying for these two examinations. If she spends 1 minutes studying for the first examination, her score on the exam will be 11 x=m 5. If she spends 2 minutes studying for the second exam, her score on this exam will be 22 x=m 10
