Hey there! I'm happy to help!
We'll call our weeks w and call our total savings s.
We have an initial $85 and then we add 7 every week. This means that we will be adding 7 for every week, so we will put this in our equation as 7w.
Therefore, our equation would be s=7w+85
Now, we plug in 8 for our w value to see how much money she will have after 8 weeks.
s=7(8)+85
s=56+85
s=141
Therefore, Aubrey will have saved $141 after 8 weeks.
I hope that this helps! Have a wonderful day! :D
Answer and Step-by-step explanation:
Simply solve for x (very easy to do).
4x + 9 = 41
<u>Subtract 9 from both sides of the equation.</u>
4x = 32
<u>Divide both sides of the equation by 4.</u>
x = 8
<u>x is equal to 8.</u>

The answer is 0.56
think of this like
14x = 25
to find x, divide 14 by 25
which will give you 0.56
to check your answer, you can just do 25 * 0.56
Based on the information given, the explanatory variable will be the SAT prep program and the response variable is the student's scores.
<h3>
Identification of the variables.</h3>
The information given is that the researcher conducts an experiment to investigate whether an SAT prep program would improve students' scores on the SAT.
The explanatory variable is the factor that is manipulated by the researcher. The response variable is the result of the experiment.
In this case, the explanatory variable is the SAT prep program and the response variable is the student's scores.
In this case, the treatment will be the 120 students that took part in the research. They're the ones that are exposed to manipulation by the researcher.
