### Example Problem:
*Problem*: Find all possible values of \( c \) such that the quadratic equation \( x^2 + cx + 49 = 0 \) has at least one real root that is an integer. Express your answer in interval notation.

### Expected Format:
*Step 1*: Understand the problem and set up the conditions for real and integer roots.  
<thinking>To find all possible values of \( c \), i need to ensure the quadratic equation has at least one real root that is an integer. This involves analyzing the discriminant and ensuring it is a perfect square. Am I confident this is the correct approach? Yes, because the discriminant determines the nature of the roots.</thinking>  
*Step 1 Confidence Score*: 0.85

*Step 2*: Calculate the discriminant and set the condition for real roots.  
<thinking>The discriminant \( D \) of the quadratic equation \( x^2 + cx + 49 = 0 \) is given by \( D = c^2 - 196 \). For the quadratic to have real roots, \( D \geq 0 \), which implies \( c^2 \geq 196 \). This step is crucial as it sets the boundaries for \( c \). Am I confident in this calculation? Yes, because it follows directly from the quadratic formula.</thinking>  
*Step 2 Confidence Score*: 0.90

*Step 3*: Ensure at least one root is an integer by analyzing the roots.  
<thinking>The roots of the quadratic equation can be expressed as \( x = \frac{-c \pm \sqrt{c^2 - 196}}{2} \). For \( x \) to be an integer, \( \sqrt{c^2 - 196} \) must be an integer. Let \( k = \sqrt{c^2 - 196} \), which leads to \( c^2 = k^2 + 196 \). This means \( c^2 \) must be a perfect square greater than or equal to 196. Am I confident this is the right approach? Yes, because it ensures the roots are integers.</thinking>  
*Step 3 Confidence Score*: 0.85

*Step 4*: Analyze perfect squares to find suitable values of \( c \).  
<thinking>We need \( k^2 \) to be a perfect square. The smallest perfect square greater than or equal to 196 is 225, leading to \( c = \pm 15 \). We continue this analysis to find all possible values of \( c \). Am I confident in this step? Yes, because it systematically checks all possible values.</thinking>  
*Step 4 Confidence Score*: 0.90

*Step 5*: Summarize the solution and express the answer in interval notation.  
<thinking>After analyzing the perfect squares, we find that the possible values of \( c \) are \( c \leq -14 \) or \( c \geq 14 \). Therefore, the answer in interval notation is \( (-\infty, -14] \cup [14, \infty) \). This final step confirms the correctness of our solution. Am I confident in the final answer? Yes, because it logically follows from the previous steps and checks.</thinking>  
*Step 5 Confidence Score*: 0.95

*Step final *: Explanation of the solution.  
<thinking>In this problem, i determined the values of \( c \) by ensuring the discriminant of the quadratic equation was a perfect square, which allowed for integer roots. By analyzing the perfect squares greater than or equal to 196, we found the intervals for \( c \). This method ensures that the quadratic equation \( x^2 + cx + 49 = 0 \) has at least one real root that is an integer.</thinking>  
*Step 6 Confidence Score*: 1.0
make sure respect this form and explanation in the end

Question: If 3 printers in an office can produce 15 documents per minute, how many printers would be needed to produce 75 documents per minute?
Answer: To determine how many printers are needed to produce 75 documents per minute, we can first calculate the production rate of one printer.

If 3 printers can produce 15 documents per minute, then one printer can produce 15 / 3 = 5 documents per minute.

To produce 75 documents per minute, we need to divide 75 by the production rate of one printer, which is 5 documents per minute.

75 / 5 = 15

Therefore, we would need 15 printers to produce 75 documents per minute.

\boxed{15}
