The answer is <span>$11.43
you type 63.50 into your calculator
then divide it by 100
the times it by 18
and you get 11.43
that is the answer</span>

Answer:
General equation of line :  --1
   --1
Where m is the slope or unit rate
Table 1)
p    d
1      3
2     6
4     12
d = Number of dollars (i.e.y axis)
 p = number of pound(i.e. x axis)
First find the slope 
First calculate the slope of given points 
 ---A
   ---A


Substitute values in A 
 
 
 
 
Thus the unit rate is 3 dollars per pound.
So, It matches the box 1 (Refer the attached figure)
Equation 1 : 
 
Since p is the x coordinate and d is the y coordinate
On Comparing with 1

Thus the unit rate is  dollars per pound
 dollars per pound
So, It matches the box 2 (Refer the attached figure)
Equation 2 : 

Since p is the x coordinate and d is the y coordinate
On Comparing with 1

Thus the unit rate is 9 dollars per pound
So, It matches the box 3 (Refer the attached figure)
Table 2)
p        d
1/9      1
1         9
2        18
d = Number of dollars (i.e.y axis)
 p = number of pound(i.e. x axis)


Substitute values in A 
 
 
 
 
 
 
Thus the unit rate is 9 dollars per pound
So, It matches the box 3 (Refer the attached figure)
 
        
                    
             
        
        
        
Answer: Santa's speed in still air is 6 miles per minute
Speed of the wind is 1 mile per minute
Step-by-step explanation:
Let x represent the speed of Santa in still air. It is assumed that in still air. She is flying with the wind. If the speed of the wind is y, then him total speed is x + y
It takes Santa 5 minutes to fly 35 miles with the wind. 
Speed = distance / time
It means that 
x + y = 35/5 = 7
It takes him 7 minutes to fly 35 miles against the wind. This means that his total speed will be x - y
Speed = distance/time. Therefore,
x - y = 35 /5 = 5 - - - - - - 1
Substituting x = 7 - y into equation 1, it becomes
7 - y - y = 5
-2y = 5 - 7 = -2
y = -2/-2 = 1
x = 7 - y = 7 - 1
x = 6
