Step-by-step explanation:
 
        
                    
             
        
        
        
When handling problems of this nature make sure you setup the equations. 
x = number of times they rent a boat. 
Members 
Cost = 105 + 9.50x
Non members because members don't have to pay the 105 we leave it out. 
Cost = 14.75x 
so now to determin when cost would be equal we set the two equations = to each other
105 + 9.50x = 14.75x 
now solve for x 
105 = 5.25x
 
20 = x 
so they would have to rent 20 times to equal each other. 
        
             
        
        
        
No. When you plug in x and y you get 2=3
        
             
        
        
        
Answer:
74
Step-by-step explanation:
You just have to substitute r with 5.
Now, the equation looks like this:

Next, solve  first according to PEMDAS
 first according to PEMDAS
And  equals 75
 equals 75
![\frac{\left[\begin{array}{ccc}1&5\\5\\\end{array}\right] }{75}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%265%5C%5C5%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%7D%7B75%7D)
Lastly, do  which equals 74
 which equals 74
![\frac{\left[\begin{array}{ccc}7&5\\-1\\\end{array}\right] }{74}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D7%265%5C%5C-1%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%7D%7B74%7D)
Therefore, 74 is your answer.
 
        
             
        
        
        
A 8p = 48.80
Since Susan paid for 8 dish towels, p. Then the 8 dish towels = $48.80
