ANSWER

EXPLANATION
The first equation is 

The second equation is 

We want to eliminate y, so we multiply the first equation by 



We now subtract equation (3) from (2) 



Multiply both sides by 



Substitute into the first equation to solve for x .

Multiply to obtain



Multiply both sides by 2.


The solution is 

 
        
                    
             
        
        
        
Answer:
C(t) = 20t
Step-by-step explanation:
The graph of C(t) appears to be linear
The y intercept is 0
The slope is 200/10 = 20
y = mx+b  where m is the slope and b is the y intercept
y = 20x+0
y = 20x
C(t) = 20t
