Introduction

In this article, we will explore the concept of calculating the total number of hours Erica works each week, considering both tutoring and babysitting hours. We will use mathematical expressions to represent the total hours worked and provide a step-by-step guide to help readers understand the concept.

Understanding the Problem

Let $x$ be the hours that Erica babysits. We are given that Erica works a certain number of hours each week, and we need to find an expression to represent the total number of hours she works. To do this, we need to consider both tutoring and babysitting hours.

Tutoring Hours

We are given that Erica works a certain number of hours each week for tutoring. Let's assume that the number of hours she works for tutoring is represented by the variable $t$ . We can represent the tutoring hours as:

$t = \text{number of hours worked for tutoring}$

Babysitting Hours

We are also given that Erica works a certain number of hours each week for babysitting. Let's assume that the number of hours she works for babysitting is represented by the variable $x$ . We can represent the babysitting hours as:

$x = \text{number of hours worked for babysitting}$

Total Hours Worked

To find the total number of hours Erica works each week, we need to add the tutoring hours and babysitting hours. We can represent the total hours worked as:

$T = t + x$

Expression for Total Hours Worked

We can rewrite the expression for total hours worked as:

$T = \text{number of hours worked for tutoring} + \text{number of hours worked for babysitting}$

Simplifying the Expression

We can simplify the expression for total hours worked by combining like terms:

$T = t + x$

Conclusion

In this article, we have explored the concept of calculating the total number of hours Erica works each week, considering both tutoring and babysitting hours. We have used mathematical expressions to represent the total hours worked and provided a step-by-step guide to help readers understand the concept.
