Let me walk through the solutions to each of the problems shown in the image.

### 1. Percentage decrease in the budget for food expenses:
- Last month, the budget was ₱25,000, and the current month's budget is ₱20,000.
- The formula for percentage decrease is:
  
  \[
  \text{Percentage Decrease} = \frac{\text{Old Value} - \text{New Value}}{\text{Old Value}} \times 100
  \]

  Substituting the values:

  \[
  \text{Percentage Decrease} = \frac{25,000 - 20,000}{25,000} \times 100 = \frac{5,000}{25,000} \times 100 = 20\%
  \]

  **Answer:** The percentage decrease in the budget for food expenses is **20%**.

### 2. Evelyn's salary decrease percentage:
- Her salary decreased from ₱38,000 to ₱35,000.
- Using the same percentage decrease formula:

  \[
  \text{Percentage Decrease} = \frac{38,000 - 35,000}{38,000} \times 100 = \frac{3,000}{38,000} \times 100 \approx 7.89\%
  \]

  **Answer:** Evelyn's salary decreased by approximately **7.89%**.

### 3. Gasoline price decrease:
- The gasoline price is currently ₱54.40 per liter, and it is expected to decrease by ₱1.10.
- To find the new price after the decrease:

  \[
  \text{New Price} = 54.40 - 1.10 = 53.30 \text{ pesos}
  \]

- The percentage decrease in price can be found as:

  \[
  \text{Percentage Decrease} = \frac{54.40 - 53.30}{54.40} \times 100 = \frac{1.10}{54.40} \times 100 \approx 2.02\%
  \]

  **Answer:** The new gasoline price will be **₱53.30** per liter, and the percentage decrease is **2.02%**.
