The answer is $80 because it's $40 per person so two people is $80
        
             
        
        
        
Answer:
y = 50x+25
f(x) = 50x+25
Step-by-step explanation:
Using the slope intercept form of the equation, y = mx+b 
where x is the amount per day and b is the flat fee
2 days
125 = 2x+b
5 days
275 = 5x+b  
Subtract
275 = 4x+b  
125 = 2x+b
---------------------
150 = 3x
Divide by 3
150/3 = 3x/3
50 =x
The cost per day is 50 dollars
y = 50x +b
Using the data for 2 days
125 = 50*2 +b
125 = 100 +b
125-100 = b
b = 25
The equation is y = 50x+25
f(x) = 50x+25
To graph, The x axis is number of days and the y axis is total cost
The number of days starts with 0, which is the y intercept
Let x = 0, y =25
Using the slope, we go 50 up and 1 to the right ( 50 dollars per day)
The next point plotted ins ( 1,50)
Draw a straight line
 
        
                    
             
        
        
        
Answer:
6 srry if dis is wrong sis 
Step-by-step explanation:
since the radius is 12 divide that by 2 and you get 6 which is the diameter. 
so im guessing the answer is 6 idk i haven't done this inna min. i hope this was helpful <3 
 
        
                    
             
        
        
        
Answer:
11
Step-by-step explanation:
11 + 8 + 14 + v + 8 + 14
==================   = 11             Combine Terms
6
(55 + v) / 6 = 11                               Multiply by 6
55 + v = 11 * 6                                 Combine the right
55 + v = 66                                     Subtract 55
55-55+v = 66- 55
v = 11
