Final answer:
The question deals with calculus, specifically the rate of change of monthly computer sales over time, which is described by the derivative S'(t).
Step-by-step explanation:
The student's question pertains to the rate of change of monthly computer sales over time, represented as S'(t), which is a concept from calculus. This is a mathematical expression of how the number of computers sold is expected to change each month. To analyze this, we apply differential calculus to determine the sales function S(t), where t represents time in months. In practical terms, this function could help predict future sales, adjust inventory levels, and create more effective marketing strategies. The rate at which sales change, S'(t), could tell us if the sales are increasing or decreasing and by how much. Understanding this rate could help a business make informed decisions.
