`{:("Quantity A","Quantity B"),((0.99)^(y),0.99xxy):}`

Answer

To compare the two quantities given in the question, we have:

- Quantity A: \( (0.99)^y \)
- Quantity B: \( 0.99 \times y \)

We need to analyze the relationship between these two quantities for different values of \( y \).

### Step 1: Evaluate for \( y = 0 \)

For \( y = 0 \):
- Quantity A:
\[ (0.99)^0 = 1 \]
- Quantity B:
\[ 0.99 \times 0 = 0 \]

**Comparison**:
\[ 1 > 0 \quad \Rightarrow \quad \text{Quantity A} > \text{Quantity B} \]

**Hint**: Remember that any non-zero number raised to the power of 0 is 1, and any number multiplied by 0 is 0.

### Step 2: Evaluate for \( y = 1 \)

For \( y = 1 \):
- Quantity A:
\[ (0.99)^1 = 0.99 \]
- Quantity B:
\[ 0.99 \times 1 = 0.99 \]

**Comparison**:
\[ 0.99 = 0.99 \quad \Rightarrow \quad \text{Quantity A} = \text{Quantity B} \]

**Hint**: When \( y = 1 \), both quantities are equal, which shows that the relationship can change based on the value of \( y \).

### Step 3: Evaluate for \( y = 2 \)

For \( y = 2 \):
- Quantity A:
\[ (0.99)^2 \approx 0.9801 \]
- Quantity B:
\[ 0.99 \times 2 = 1.98 \]

**Comparison**:
\[ 0.9801 < 1.98 \quad \Rightarrow \quad \text{Quantity A} < \text{Quantity B} \]

**Hint**: As \( y \) increases, \( 0.99 \times y \) increases linearly, while \( (0.99)^y \) decreases exponentially.

### Conclusion

From the evaluations:
- For \( y = 0 \): Quantity A > Quantity B
- For \( y = 1 \): Quantity A = Quantity B
- For \( y = 2 \): Quantity A < Quantity B

Since the relationship between Quantity A and Quantity B varies depending on the value of \( y \), we cannot determine a consistent relationship between the two quantities.

Thus, the answer is:
**Option D: The relationship cannot be determined from the information given.**
