Introduction

In construction projects, managing time and work done is crucial for meeting deadlines and staying within budget. Ed, a project manager, is tasked with overseeing a construction project and needs to understand the relationship between the percentage of work done and the number of weeks since the project started. The function $y = 0.75x$ represents this relationship, where $y$ is the percentage of work done and $x$ is the number of weeks since the project started. In this article, we will explore the value represented by the coefficient 0.75 in the function.

The Function $y = 0.75x$

The function $y = 0.75x$ is a linear equation that describes the relationship between the percentage of work done ( $y$ ) and the number of weeks since the project started ( $x$ ). The coefficient 0.75 represents the rate at which the work is being done. In other words, for every week that passes, 0.75% of the work is completed.

Interpreting the Coefficient 0.75

The value 0.75 can be interpreted in two ways:

Rate of Work Completion: As mentioned earlier, the coefficient 0.75 represents the rate at which the work is being done. It means that for every week that passes, 0.75% of the work is completed.
Proportion of Work Done: The value 0.75 can also be seen as a proportion of the work done. It means that after 1 week, 0.75% of the work is completed, after 2 weeks, 1.5% of the work is completed, and so on.

Understanding the Relationship Between Work Done and Time

The function $y = 0.75x$ shows a direct relationship between the percentage of work done and the number of weeks since the project started. This means that as the number of weeks increases, the percentage of work done also increases at a constant rate.

Example

Let's consider an example to illustrate this relationship. Suppose the project started 4 weeks ago, and the function $y = 0.75x$ is used to calculate the percentage of work done. We can plug in the value of $x$ (4 weeks) into the function to get:

$y = 0.75 \times 4 = 3$

This means that after 4 weeks, 3% of the work is completed.

Conclusion

In conclusion, the value 0.75 in the function $y = 0.75x$ represents the rate at which the work is being done. It means that for every week that passes, 0.75% of the work is completed. Understanding this relationship is crucial for project managers like Ed to plan and manage their construction projects effectively.
