Business and Economics

Algebra for Decision Making

Companies use algebra to maximize profit, minimize costs, and set prices.

How It Works

  • Linear equations model revenue and expenses.
  • Systems of equations balance supply and demand.

Real-World Impact

Mastering these skills can help you run a business or understand the economy better.

Examples

  • Profit = Revenue - Costs: If revenue is \(R = 20x\) and cost is \(C = 15x + 100\), then profit is \(P = R - C = 5x - 100\).

  • A store must sell at least 200 units to break even: \(20x = 4000\), so \(x = 200\).
