The problem you've provided is about calculating interest on a loan. Here's the key information:

- Loan amount (Principal): Fr. 5500
- Loan duration: 7 months
- Interest rate: 3%

### To solve this:
We need to calculate the total interest and the final amount G. Gimenez will receive back.

1. **Convert the interest rate for 7 months**:  
   The interest rate is given as an annual rate (3%), but since the loan duration is 7 months, we adjust the interest rate proportionally.

   \[
   \text{Monthly interest rate} = \frac{3\%}{12} = 0.25\%
   \]

   For 7 months:
   \[
   \text{Effective interest rate for 7 months} = 7 \times 0.25\% = 1.75\%
   \]

2. **Calculate the interest**:  
   Using the simple interest formula:
   \[
   \text{Interest} = \text{Principal} \times \text{Rate}
   \]
   where Rate is the effective interest rate for 7 months (1.75%).

   \[
   \text{Interest} = 5500 \times \frac{1.75}{100} = 96.25 \text{ Fr.}
   \]

3. **Final amount**:  
   The total amount G. Gimenez will receive back is the principal plus the interest:

   \[
   \text{Final amount} = 5500 + 96.25 = 5596.25 \text{ Fr.}
   \]

So, G. Gimenez will receive **Fr. 5596.25** after 7 months.

Here are 5 related questions for practice:
1. How would the final amount change if the loan duration was 12 months instead of 7?
2. What would the final amount be if the interest rate was 4% instead of 3%?
3. How would you calculate the monthly interest rate if the loan was compounded monthly?
4. What is the difference between simple and compound interest in this scenario?
5. If the principal amount was Fr. 7000 instead of Fr. 5500, what would the new final amount be?

**Tip:** Always ensure you adjust the annual interest rate according to the time period of the loan when calculating simple interest.
