0.05x + 0.08(10,000 - x) = 680

Understanding the Equation: Solving 0.05x + 0.08(10,000 - x) = 680

When faced with a linear equation like 0.05x + 0.08(10,000 - x) = 680, it might seem daunting at first—but breaking it down step by step makes solving it straightforward. Whether you're a student learning algebra or a professional working through real-world financial calculations, understanding how to solve equations systematically is essential.

Understanding the Context

What is the Equation?

The equation 0.05x + 0.08(10,000 - x) = 680 models a weighted average scenario, commonly used in finance, cost analysis, or profit modeling. It balances two different rates applied to parts of a total quantity.

In this case:
- 0.05x represents 5% of a quantity x
- 0.08(10,000 - x) represents 8% applied to the remaining (10,000 - x)

Their sum equals 680, likely modeling a total weighted cost or return.

Step 1: Expand the Expression

Start by distributing 0.08 across the parenthesis:

\[
0.05x + 0.08 \ imes 10,000 - 0.08x = 680
\]

Calculate \(0.08 \ imes 10,000 = 800\), so the equation becomes:
