Answer :
To find out how many hours Jenna babysits per week, we need to consider the hours she works each night.
1. Babysitting for 1 night a week:
- Jenna babysits for 2 hours on one night every week.
2. Babysitting for 3 nights a week:
- Jenna babysits for [tex]\(4 \frac{1}{4}\)[/tex] hours each night, and she does this for 3 nights a week.
- The mixed number [tex]\(4 \frac{1}{4}\)[/tex] is equivalent to the decimal 4.25 hours (since [tex]\(\frac{1}{4}\)[/tex] equals 0.25).
3. Calculate total weekly hours:
- First, compute the total hours for the 3 nights:
- Multiply the hours per night by the number of nights: [tex]\(4.25 \times 3 = 12.75\)[/tex] hours.
- Then, add the hours for the 1 night to the total for the 3 nights:
- [tex]\(2 \, \text{hours} + 12.75 \, \text{hours} = 14.75 \, \text{hours}\)[/tex].
Therefore, Jenna babysits a total of 14.75 hours per week.
