So, its time to do some MATH!
ok so i would first approach this problem by placing the prices in order from least to greatest......um it would look something like this...(cue the math skills in my brain)
1.29,1.59,1.99,2..09, and last but most definitely not least (get it?) 2.19
so basically the median is like the MIDDLE number of your data (shout out to my fellow middle children!)
and so you may be asking "how does one figure this out?" and i will tell you that it is quite simple...
so what you got to do is cross out a number from the left and a number from the right, and you will be left with one number, which is your middle number (or in fancy maths language -the median- that was supposed to be said with a British accent, so just bear with me there :-))
and so your final answer should be....(drumroll please)
$1.99 is your median
(ta- da you are supermathematicalgeniuslevel smart)

Step-by-step explanation:

In looking at it I would guess it is asking which of the points is on the line? To answer that you would have to take each point an plug it into the equation and see if it is true.
3x - 7 = y
A(9,20)
3(9) - 7 = 20
27 - 7 = 20
20 = 20 True - this point is on the line
B(5,0)
3(5) - 7 = 0
15 - 7 = 0
8 = 0 False - this point is not on the line
C(3,2)
3(3) - 7 = 2
9 - 7 = 2
2 = 2 True - this point is on the line
I hope this helps
Answer:
3x−4y=9 −3x+2y=9
Add these equations to eliminate x: −2y=18
Then solve−2y=18
for y: −2y=18 −2y −2 = 18 −2 (Divide both sides by -2)
y=−9
Now that we've found y let's plug it back in to solve for x.
Write down an original equation: 3x−4y=9
Substitute−9for y in 3x−4y=9: 3x−(4)(−9)=9
3x+36=9(Simplify both sides of the equation)
3x+36+−36=9+−36(Add -36 to both sides)
3x=−27 3x 3 = −27 3 (Divide both sides by 3) x=−9
Answer: x=−9 and y=−9
