Chapter 1: Problem 9

A company posted a net loss of \(\$ 3\) billion during the 3rd quarter. During the same quarter, the company's revenue was \(\$ 5\) billion. a. What was the company's cost in the 3 rd quarter? b. Assuming \(R(t)\) represents revenue and \(P(t)\) represents profit during the \(t\) th quarter, write an expression for cost.

Short Answer

Expert verified
a. \$8 billion, b. \( C(t) = R(t) - P(t) \).

Step by step solution

01

Understand Definitions

To solve part (a) and (b), recall that profit (net loss is negative profit) given as \( P(t) \) is equal to revenue \( R(t) \) minus cost \( C(t) \). Thus, \( P(t) = R(t) - C(t) \). The profit here is negative (a net loss of \$3 billion), meaning \( P(t) = -3 \) billion and \( R(t) = 5 \) billion.
02

Solve for Cost in the 3rd Quarter

Use the equation from Step 1, substituting the given figures: \( -3 = 5 - C(t) \). Rearranging this equation, we get \( C(t) = 5 + 3 = 8 \) billion. Therefore, the cost during the 3rd quarter was \$8 billion.
03

Write Expression for Cost

Based on the equation \( P(t) = R(t) - C(t) \), we rearrange to express cost as \( C(t) = R(t) - P(t) \). This formula will allow calculation of cost when the revenue and profit are known.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Profit and Loss Calculation
Profit and Loss Calculation is a fundamental concept in business, showing how well a company is performing financially. The profit is what remains after subtracting costs from revenue, while a loss occurs when costs surpass revenue. In the original exercise context, the company faced a net loss of \( \$3 \) billion, indicating that its operating costs exceeded its revenue in the 3rd quarter.

To mathematically represent this, the relationship between profit \(P(t)\), revenue \(R(t)\), and cost \(C(t)\) is key:
  • Profit or Loss \( P(t) = R(t) - C(t) \)
  • Negative profit signifies a net loss
Getting a clear grasp of these calculations will significantly aid in understanding a company's financial standing.
Revenue Analysis
Revenue Analysis is crucial to comprehend a company's performance. Revenue, often called sales, is the income from normal business activities. In our exercise scenario, the company's revenue in the 3rd quarter was \( \$5 \) billion.

Revenue serves as a starting point in the profit calculation. It must exceed costs to achieve a profit. Otherwise, the company endures a loss. Understanding revenue involves:
  • Investigating sales trends over time
  • Evaluating the effectiveness of pricing strategies
  • Ensuring revenue aligns with business goals
Effective revenue analysis offers insights into whether the company is achieving its financial targets and market position.
Cost Function
The Cost Function is essential for determining how expenses impact a business's profitability. Costs include all expenses to produce goods and services. In the exercise, the cost in the 3rd quarter was deduced to be \( \$8 \) billion using the equation for profit.

The equation \( P(t) = R(t) - C(t) \) can be rearranged to express cost, \( C(t) = R(t) - P(t) \), allowing us to find the cost when profit and revenue are known.
  • Use this formula to calculate costs from known profit/loss and revenue
  • Analyze changes in costs for better budgeting
  • Identify areas to reduce expenses
Understanding the cost function assists businesses in maintaining control over their finances, ultimately leading to better profit management.
