2. Plan 2:
- Monthly savings: [tex]$5 - Duration: 25 months To find the total savings for this plan, we multiply the monthly savings by the number of months: \(5 \times 25 = 125\) So, the savings for this plan are $[/tex]125.

3. Plan 3:
- Monthly savings: [tex]$10 - Duration: 25 months To find the total savings for this plan, we multiply the monthly savings by the number of months: \(10 \times 25 = 250\) So, the savings for this plan are $[/tex]250.

4. Plan 4:

In summary, the total savings for each plan are:
- Plan 1: [tex]$100.08 - Plan 2: $[/tex]125
- Plan 3: [tex]$250 - Plan 4: $[/tex]216
