Answer:
.
Step-by-step explanation:
The linear approximation is given by the equation
                             
Linear approximation is a good way to approximate values of 
 as long as you stay close to the point 
, but the farther you get from 
, the worse your approximation.
We know that,

Next, we need to plug in the known values and calculate the value of 
:

Then
.
 
        
             
        
        
        
C The answer is y=1.560-22.105
        
                    
             
        
        
        
The finance Charge would be $140. you would multiply 18 by 80 and then add the 130 and take that number and subtract the 1,430
