Answer:
The total amount due after five years is $57,000. 
Step-by-step explanation:
Recall that simple interest is given by the formula: 

Where <em>A</em> is the final amount, <em>P</em> is the principal amount, <em>r</em> is the rate, and <em>t</em> is the time (in years). 
Since we are investing a principal amount of $38,000 at a rate of 10.0% for five years, <em>P</em> = 38000, <em>r</em> = 0.1, and <em>t</em> = 5. Substitute: 

Evaluate. Hence: 

The total amount due after five years is $57,000. 
 
        
             
        
        
        
10/12= $.83 per inch
20/18= $1.11 per inch
        
                    
             
        
        
        
Given data:
The first point given iis (a, b)=(-6,2).
The second point given is (c,d)=(0, -6).
The expression for the slope is,
m=(d-b)/(c-a)
Substitute the given points in the above expression.
m=(-6-2)/(0-(-6))
=(-8)/(6)
=-4/3
Thus, the slope of the line is -4/3, so (C) option is correct.
