Write the Inequality for the product of a number and 8 is at least 25.

We will be using the concept of inequalities to solve this.

Answer: The inequality for the product of a number(Z) and 8 is at least 25 is Z ≥ 25/8.

Let's solve this step by step.

Explanation:

Let Z be the unknown number.

Given that, Z × 8 is at least 25

⇒ 8Z can be greater than or equal to 25.

According to the definition of inequalities:

8Z ≥ 25

⇒ Z ≥ 25/8 

Thus, the inequality for the product of a number(Z) and 8 is at least 25 is Z ≥ 25/8.
