Final answer:
The equation is c * 2 = 30. To translate the sentence into an equation, use the variable c to represent Craig's height.
Step-by-step explanation:
To translate the sentence into an equation, we can use the variable c to represent Craig's height. The sentence states that the product of Craig's height and 2 is 30. In mathematical terms, this can be written as:
c * 2 = 30
This equation represents the relationship between Craig's height (c) and the value 30, where 2 times Craig's height is equal to 30.
