Let's analyze and solve the questions 35 to 39 based on the data provided in the image.

### Provided Table:
The table contains information for four months on the following criteria:
1. **Actual Revenue (y):** Revenue obtained each month.
2. **Planned Revenue (y'):** Targeted or planned revenue each month.
3. **Growth Rate of Actual Revenue (r%):** Percentage growth of actual revenue compared to the previous month.
4. **Growth Rate of Planned Revenue (r'%):** Percentage growth of planned revenue compared to the previous month.

### Information in the Table:

| Criteria                               | Month 1 | Month 2 | Month 3 | Month 4 |
|----------------------------------------|---------|---------|---------|---------|
| 1. Actual Revenue (y)                  | 310     | 370     | 420     | 450     |
| 2. Planned Revenue (y')                | 320     | 400     | 450     | 480     |
| 3. Growth Rate of Actual Revenue (r%)  | -       | 19.35%  | 13.51%  | 7.14%   |
| 4. Growth Rate of Planned Revenue (r'%)| -       | 25%     | 12.5%   | 6.67%   |

### Questions and Solutions:

#### **Question 35:**
Calculate the cumulative actual revenue for the first 4 months.

- Add the actual revenues for each month:
  
  \[
  310 + 370 + 420 + 450 = 1550 \text{ billion VND}
  \]

  **Answer:** B. 1550 billion VND

#### **Question 36:**
Calculate the cumulative planned revenue for the first 4 months.

- Add the planned revenues for each month:
  
  \[
  320 + 400 + 450 + 480 = 1650 \text{ billion VND}
  \]

  **Answer:** A. 1650 billion VND

#### **Question 37:**
Determine the actual revenue growth rate from month 1 to month 4.

- The formula to calculate the cumulative growth rate over a period is:

  \[
  \text{Growth Rate} = \left(\frac{\text{Final Value}}{\text{Initial Value}} - 1\right) \times 100
  \]

  Here, from month 1 to month 4:
  
  \[
  \text{Growth Rate} = \left(\frac{450}{310} - 1\right) \times 100 = \left(\frac{450}{310}\right) \times 100 - 100
  \]
  
  \[
  = 1.4516 \times 100 - 100 = 45.16\%
  \]

  **Answer:** A. 45.16%

#### **Question 38:**
Calculate the difference between the actual and planned revenue for month 4.

- Difference = Planned Revenue (y') - Actual Revenue (y)
  
  \[
  \text{Difference} = 480 - 450 = 30 \text{ billion VND}
  \]

  **Answer:** C. 30 billion VND

#### **Question 39:**
Find the planned revenue growth rate from month 1 to month 4.

- Similar to Question 37, calculate the growth rate:

  \[
  \text{Growth Rate} = \left(\frac{480}{320} - 1\right) \times 100 = \left(\frac{480}{320}\right) \times 100 - 100
  \]
  
  \[
  = 1.5 \times 100 - 100 = 50\%
  \]

  **Answer:** C. 50%
