Final answer:
To solve for s in the equation k = sc, you need to isolate s. The correct answer is s = k/c.
Step-by-step explanation:
To solve for s in the equation k = sc, you need to isolate s.
To do this, divide both sides of the equation by c, resulting in the equation:
s = k/c
Therefore, the correct answer is s = k/c (option b).
