Answer:
The exact interest on $5,870 at 12% is $410.9
Step-by-step explanation:
From the information provided we know that
Principal amount: $5,870
Interest rate: 12% -> 0.12
Time: 7 months (From June to December)
When you know the principal amount, the rate, and the time, the amount of interest can be calculated by using the formula:

where P is principal, r is the rate of interest and t is the time in years.
We need to convert the 7 months into 1 year.

Now we can use the above formula

Therefore the exact interest on $5,870 at 12% is $410.9
 
        
             
        
        
        
The alphabet has 26 letters
        
                    
             
        
        
        
100 is the common denominator so
70/100 + 20/100 90/100 = 9/10
        
                    
             
        
        
        
The answer is b. k=64 t=52.
