Therefore, Alana earns $23 for walking 23 km. Therefore, Alana walks 73.5 km if she earns $60.

An equation is a mathematical statement that shows that two expressions are equal. It usually consists of variables, coefficients, and mathematical operations such as addition, subtraction, multiplication, and division. An equation can be solved to find the value of the variable that makes the statement true. Equations can be represented using symbols, such as the equals sign (=), or written out in words. Equations are used in many areas of mathematics and other fields, such as physics, engineering, and finance, to model and solve real-world problems.

Here,

To find the amount of money Alana earns for walking 23 kilometers, we can use interpolation method on the given table.

First, we need to find the interval in which 23 km falls, which is between 4 km and the unknown value x.

Next, we need to find the corresponding interval for the amount earned, which is between 7 dollars and an unknown value y.

Using the formula for interpolation, we can find the value of y as follows:

y = 7 + [(23-4)/(x-4)] * (16.5-7)

Simplifying this equation and solving for x, we get:

x = 37 km

Therefore, Alana earns $23 for walking 23 km.

To determine how far Alana walks if she earns $60, we can use extrapolation method on the given table.

First, we need to find the interval in which 60 dollars falls, which is between 16.5 dollars and an unknown value z.

Next, we need to find the corresponding interval for the distance walked, which is between 10 km and an unknown value w.

Using the formula for extrapolation, we can find the value of w as follows:

w = 10 + [(60-16.5)/(z-16.5)] * (x-10)

Simplifying this equation and solving for z, we get:

z = 73.5 dollars

Therefore, Alana walks 73.5 km if she earns $60.

It's worth noting that interpolation and extrapolation methods are approximations and may not be completely accurate.

IF YOU CAN DO THIS FOR ME IT WOULD REALLY HELP!!!
THE QUESTION I CHOSE IS IN THE COMMENTS BELOW!!!

Introduction: In your introduction, you will explain in complete sentences what you were trying to accomplish through the project. You will explain the question you were trying to answer, as well as "why" you selected that question.

Methods: In this section, you need to explain the methods that you used in the data collection project. This explanation needs to include a description of the population, the sample, and the sampling methods. You also need to include the survey question in this section. You can include the survey question right in the text, or if you used a document to pass out your survey or online form, you can reference the document or the online form (provided the document or form is included in your report in some way whether through an appendix or separate document that is referenced in the Methods section).

Data: In the data section, you will not only include your frequency table and graph, but you will also include a written description of the results. Since this is the "data" and not the "conclusion," just talk about the sample population in this section. Answer the question "What were the results of the survey?" in this section.

Conclusion: Now you will have a written description of the generalizations that you made from looking at the data. This is where you would use language that applies the results to the larger population. You can use language like "On the basis of these findings." or "The results of this survey suggest." You should also include some mathematical examples of how the data applies to the larger population.
