Step-by-step explanation:
Calculating Time Spent on Activities
To find out how many hours Mr. Perfecto spends on each activity in a week, we first need to know the total number of hours in a week. There are 24 hours in a day and 7 days in a week, so a week consists of 24 * 7 = 168 hours. Now, let's calculate the time spent on each activity.
Planning: 10.5% of 168 hours = 0.105 * 168 = 17.64 hours
Working: 35% of 168 hours = 0.35 * 168 = 58.8 hours
Computer games: 1/5 of 168 hours = 0.2 * 168 = 33.6 hours
Sleeping: 1/3 of 168 hours = 0.333... * 168 = 56 hours
Mr. Perfecto spends 17.64 hours planning, 58.8 hours working, 33.6 hours playing computer games, and 56 hours sleeping in a week.
