Answer:
The principal amount was $23,393.45
Step-by-step explanation:
The total amount paid on a 35 year loan was $98,000 at the rate of interest 4.1%
We will calculate Principal amount by this formula 

Where A = amount (98,000)
            P = Principal amount (P)
            r = rate of interest 4.1% (0.041)
            n = number of compounding interest monthly (12)
            t = time (35 years)



98,000 = P(4.189386)
= 4.189386P = 98,000
P = 
P = 23,392.4494 ≈ $23,392.45
The principal amount was $23,393.45
 
        
                    
             
        
        
        
Answer C. The pattern is that each number in sequence 1 is being doubled to get the number in sequence 2, and 40*2=80
        
             
        
        
        
You’d have to try to get r on one side of the equation. 
You can do that by subtracting 12 from both sides which would make it so 
R = -9
