Answer :
To find out how many hours you have left for other activities during the week if you sleep eight hours a day, follow these steps:
1. Calculate Total Weekly Hours:
- There are 24 hours in a day.
- There are 7 days in a week.
- Multiply the total hours per day by the number of days in a week:
[tex]\[
24 \, \text{hours/day} \times 7 \, \text{days/week} = 168 \, \text{hours/week}
\][/tex]
2. Calculate Total Sleep Hours in a Week:
- You sleep 8 hours per day.
- Multiply the sleep hours per day by the number of days in a week:
[tex]\[
8 \, \text{hours/day} \times 7 \, \text{days/week} = 56 \, \text{hours/week}
\][/tex]
3. Calculate Hours Left for Other Activities:
- Subtract the total weekly sleep hours from the total weekly hours:
[tex]\[
168 \, \text{hours} - 56 \, \text{hours} = 112 \, \text{hours}
\][/tex]
So, you have 112 hours left for other activities during the week. The correct answer is b) 112 hours.
