Use the five steps for problem solving.
Enrollment at a particular online university is 11,600. There are seven times as many students who work full time as there are students who do not. How many students work full time and how many do not?
Didn't you understand my answer to your previous post about this question?

Instead of reposting a question that's already been answered, please ask your questions about it in the same thread.
No, Ms. Sue I did not.
Which part of this do you not understand?
Let x = the number of students who do not work full time.
x + 7x = 11,600
8x = 11,600
x = 1,450
Try this:
Let the number of students who do not work be x
then the number of students who work = 11600-x
You said:
"There are seven times as many students who work full time as there are students who do not"
or
The number of students who work is 7 times the number of students who don't work ----> 11600 - x = 7x
or 7x + x = 11600
which is the equation that Ms Sue gave you
The five steps for problem solving can be used to solve the given question. Let's go through each step:
Step 1: Understand the problem
In this step, we need to fully understand the question. The problem states that the enrollment at a particular online university is 11,600. It also tells us that there are seven times as many students who work full time as there are students who do not. We need to find out the number of students who work full time and the number of students who do not.
Step 2: Devise a plan
Once we understand the problem, we need to come up with a plan to solve it. In this case, we can set up equations to represent the given information and then solve them to find the answer.
Step 3: Carry out the plan
Now, let's use the information given in the problem to set up equations. Let's say the number of students who do not work full time is x. Then, the number of students who work full time would be 7x (seven times as many).
According to the problem, the total enrollment is 11,600. So we can write the equation: x + 7x = 11,600
Step 4: Look back
After solving the problem, it's important to look back and check if the answer makes sense. In this case, we should ensure the answer satisfies the given conditions. For example, if we find that the number of students who work full time is negative, it would not make sense, so we should revisit our calculations.
Step 5: Communicate the solution
Finally, communicate the solution in a clear and concise manner. In this case, after solving the equation, we can determine the values of x (students who do not work full time) and 7x (students who work full time).
Let's solve the equation:
x + 7x = 11,600
8x = 11,600
x = 11,600 / 8
x = 1,450
So, there are 1,450 students who do not work full time, and since there are seven times as many students who work full time, there would be 7 * 1,450 = 10,150 students who work full time.
Therefore, there are 1,450 students who do not work full time, and 10,150 students who work full time at the online university.
