Answer:
Find the median of this data
21+23+60+60+50+54+54+59+26+15+43+15=480/ 12 = 40
Now the median should be 50 so take 50 - 40 = 10
The missing number from the data is 10
7 x 4 = 28
Santiago has a total of $28.
I believe you would create and equation to find x and y.
Given two points:
A(x₁,y₁) and B(x₂,y₂) the midpoint would be:
M((x₁+x₂)/2 , (y₁+y₂)/2)
In this case:_
A(-2,6) and B(4,-2); the midpoint would be:
M((-2+4)/2 , (6-2)/2)=(1,2)
Answer: the midpoint of AB is (1,2)
1/3 ÷ 3 =

for each
Luke will stay with a total of:

(x 3) =
