Introduction

Charlie's daily routine involves cycling a fixed distance of 9 miles every day. This consistent behavior raises an interesting question: how can we mathematically model Charlie's daily mileage? In this article, we will explore the relationship between the number of days Charlie cycles and the total miles he covers.

Analyzing the Data

To create a mathematical model, we need to analyze the given data. The table below shows the number of days Charlie cycles and the corresponding total miles he covers.

Days (d)	Miles (m)
1	9
2	18
3	27
4	36
5	45

Identifying the Pattern

Upon examining the data, we notice a clear pattern. The total miles Charlie covers each day is increasing by 9 miles. This suggests a linear relationship between the number of days and the total miles.

Creating the Equation

To create an equation that models Charlie's daily mileage, we need to identify the variables and the relationship between them. Let's denote the number of days as 'd' and the total miles as 'm'. We can see that the total miles is equal to the number of days multiplied by 9.

The Equation

Based on the analysis, we can create the following equation:

m = 9d

This equation models the situation, where 'm' represents the total miles Charlie covers and 'd' represents the number of days he cycles.

Discussion

The equation m = 9d is a simple linear equation that describes the relationship between the number of days and the total miles Charlie covers. This equation can be used to predict the total miles Charlie will cover on any given day.

Conclusion

In conclusion, we have successfully created a mathematical model to describe Charlie's daily mileage. The equation m = 9d accurately represents the relationship between the number of days and the total miles Charlie covers. This model can be used to make predictions and understand Charlie's cycling behavior.
