Monday=x
a+15=32
a=17
That is your answer.
Answer:
There are a couple different solutions to your equation:

![x=\sqrt[22]{\frac{13}{n}}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B22%5D%7B%5Cfrac%7B13%7D%7Bn%7D%7D)
![x=-\sqrt[22]{\frac{13}{n}}](https://tex.z-dn.net/?f=x%3D-%5Csqrt%5B22%5D%7B%5Cfrac%7B13%7D%7Bn%7D%7D)

The value of x at equal total cost is 266.67
Here, we want to solve the equation to get the x-value that shows the total costs for the two companies are equal
We proceed as follows;
Considering that each student has only one birthday, each input will be related to only one output, hence this relation is a function.
<h3>When does a relation represent a function?</h3>
A relation represents a function when each value of the input is mapped to only one value of the output.
For this problem, we have that:
- The input is the student's name.
- The output is the student's birthday.
Each student has only one birthday, hence each input will be related to only one output, hence this relation is a function.
