Given:
Admission to the local movie theater is $3 for each child and $7 for each adult.
A group of 12 people pay $64 admission.
To find:
The number of children in a group.
Solution:
Let the number of children be x and number of adults be y.
According to the question,
Total persons : ...(i)
Total cost : ...(ii)
Multiply equation (i) by 7 and subtract the result from (ii).
Divide both sides by -4.
Therefore, the number of children is 5.

Answer:
Mean: 35
Median: 31
Mode: 36.9 (If you round up), 36.8 (If you don't round up)
Step-by-step explanation:
Order the Data: 29, 30, 30, 31, 31, 35, 35, 35, 36
Mean: Average , sum all of your data and divided by how many scores are in your data. (From Math Notes I have)
332/9 = 36.9 (If you round up)
Median: Middle Score (From Math Notes I have)
In this case the Median is 31.
Mode: The score that up most (From Math Notes I have)
In this case the Mode is 35.
One possible system is
1x + 3y = 4
2x + 6y = 8
Note how 2 is twice as large as 1, 6 is twice as large as 3, and 8 is twice as large as 4.
In other words, the second equation is the result of multiplying both sides of the first equation by 2.
1x+3y = 4
2*(1x+3y) = 2*4
2x+6y = 8
Effectively the two equations in bold are the same which produces the same line. The two lines overlap perfectly to intersect infinitely many times. An intersection is a solution.
