Answer:
1. Identify the unknown number: Let's represent the unknown number as "x".
2. Understand the given information: The phrase states that the product of the unknown number (x) and 8 is at least 104.
3. Translate the phrase into an inequality: The phrase "at least" suggests that the product must be greater than or equal to 104. Therefore, we can write the inequality as:
8x ≥ 104
This inequality states that when we multiply the unknown number (x) by 8, the result must be greater than or equal to 104.
In summary, the inequality that represents the phrase "the product of a number and 8 is at least 104" is 8x ≥ 104.
