manufacturing company produces electronic ahis case study examines the practical application of differentiation and integration in Economics and Commerce, particularly in business decision-making related to cost, revenue, pricing, and market surplus. A manufacturing firm operates in a competitive market and aims to determine its optimal production level and pricing strategy. The firm൙s cost and revenue behavior are expressed through marginal functions, which represent the rate of change of total cost and total revenue with respect to output. Using the concept of integration, students are required to derive: The Total Cost function from the Marginal Cost function The Total Revenue function from the Marginal Revenue function The Demand function from the Revenue relationship Using the concept of differentiation, students analyze: Profit maximization condition (MR = MC) Equilibrium output and price Further, applying definite integrals, students calculate: Consumer Surplus (area between demand curve and price line) Producer Surplus (area between price line and supply/marginal cost curve) need completequestion
