Javier rates his work-readiness on a scale from 0 to 10 points, with 10 being maximum readiness. He wants his rating to be as high as possible when he arrives at his office and has found that the rating is affected by how late he sleeps and how long he spends preparing for work. His alarm clock sounds at 6 a.m., at which time he has a work-readiness rating of 10. He needs to leave for work at exactly 6:40 am. During these 40 minutes, Javier's only activities are sleeping or preparing for work.If Javier spends more than 25 minutes or less than 10 minutes to prepare, his rating is reduced by 5 points. To sleep past 6 a.m., however, Javier must use the snooze button on his alarm clock, which delays the alarm by 4 minutes. Each press of the snooze button after the third will decrease Javier's efficiency rating by 1 point.In the following table, select for rating the greatest work-readiness rating that Javier can achieve and select for Snoozes the number of times he must press the snooze button to achieve that rating. Make only two selections, one in each column.
