MUxMUy=PxPythe fraction with numerator cap M cap U sub x and denominator cap M cap U sub y end-fraction equals the fraction with numerator cap P sub x and denominator cap P sub y end-fraction If , and I = $100. MUxcap M cap U sub x MUycap M cap U sub y Set up ratio: Substitute into Budget constraint: 3. Production and Costs: Profit Maximization microeconomics with simple mathematics pdf

In a perfectly competitive market, firms are price takers. Because an individual firm can sell any quantity at the market price, its total revenue is simply Taking the derivative gives: MR=Pcap M cap R equals cap P Therefore, a competitive firm maximizes profit where: P=MCcap P equals cap M cap C

Ymax=IPycap Y sub max end-sub equals the fraction with numerator cap I and denominator cap P sub y end-fraction Utility and Optimal Choice

Consumers aim to maximize utility (satisfaction) subject to a budget constraint. Key Concepts Using basic algebra, this can be rewritten using

Finally, simple mathematics serves as the language of market equilibrium. The famous Marshallian Cross, the intersection of supply and demand curves, is the iconic image of economics. Here, the algebraic equations for supply ($Q_s = c + dP$) and demand ($Q_d = a - bP$) are solved simultaneously to find the equilibrium price and quantity. This intersection represents a state of rest where the intentions of buyers match the intentions of sellers. The simple manipulation of these equations allows economists to predict the effects of government intervention, such as price ceilings or taxes. For instance, calculating the deadweight loss of a tax involves computing the area of a triangle, a geometric exercise that reveals the loss of total societal welfare that occurs when market distortions prevent mutually beneficial trades.
