Problem 1:
Susan jogged 3.7 miles every day for 4 days. On the fifth day, she jogged 2.8 miles. What is the total distance she covered during the five days?
#### Step-by-Step Solution:
1.
Calculate the distance jogged in the first 4 days:
- Susan jogged 3.7 miles each day for 4 days.
- Total distance for 4 days = \( 3.7 \times 4 \)
- \( 3.7 \times 4 = 14.8 \) miles
2.
Add the distance jogged on the fifth day:
- On the fifth day, Susan jogged 2.8 miles.
- Total distance for 5 days = Distance for 4 days + Distance on the fifth day
- Total distance = \( 14.8 + 2.8 \)
- \( 14.8 + 2.8 = 17.6 \) miles
#### Final Answer:
\[
\boxed{17.6}
\]

Problem 2:
Lauren spent $15.2 in all. She spent half of the total money to buy a packet of gums. If each gum in the packet costs $1.9, how many gums are there in the packet?
#### Step-by-Step Solution:
1.
Calculate the amount spent on the packet of gums:
- Lauren spent half of her total money on the packet of gums.
- Total money spent = $15.2
- Amount spent on gums = \( \frac{15.2}{2} \)
- \( \frac{15.2}{2} = 7.6 \) dollars
2.
Determine the number of gums in the packet:
- Each gum costs $1.9.
- Number of gums = \( \frac{\text{Amount spent on gums}}{\text{Cost per gum}} \)
- Number of gums = \( \frac{7.6}{1.9} \)
- Perform the division: \( 7.6 \div 1.9 = 4 \)
#### Final Answer:
\[
\boxed{4}
\]
---
Summary of Solutions:
1. The total distance Susan covered in five days is \(\boxed{17.6}\) miles.
2. The number of gums in the packet is \(\boxed{4}\).
