Answer:

Adult ticket: $7 Student ticket: $11

Step-by-step explanation:

First, we set up our equations.

x (adult ticket) y(student ticket)

For the first day, 11x + 3y = 110

For the second day, 3x + 6y = 87

Then we solve.

(-2)11x + 3y =110

Equals

-22x - 6y = -220

Add them

-22x - 6y = -220

3x + 6y = 87

This equals

-19x = -133

x = 7

Plug in to find y

3(7) + 6y = 87

21 + 6y = 87

6y = 66

y= 11

11a + 3s = 110
3a +6s = 87

-22a - 6s = -220
3a + 6s = 87

-19a = -133

a = $7 adult ticket

3(7) + 6s = 87

21 + 6s = 87

6s = 66

s = $11 student ticket

Question 7 (5 points)
Arada [10]

Answer: 6

That chart is confusing ash, but median just refers to the middle value. Just put them in order (4,4,6,9,12) and then find the middle. In this case it's easy as there are an odd number of values. But if you have another question where there are an odd number, for example (4,4,6,10,12,15) find the two middle numbers, 4 and 9, add them (6+10=16) and then divide by 2 to find the number in between those two. (16/2=8)

Hope this helps!
