Answer:
$54.6
Step-by-step explanation:
Amount borrowed = $560
Interest paid in the 12-month period = 6.5% of 560 =$36.4
The amount of interest Trudy pays in 18 months is worked out as
Monthly interest = $36.4/12
Interest payable in 18 months
 = ($36.4/12) x 18
 = $54.6
 
        
             
        
        
        
Answer:
Repeating decimal
Step-by-step explanation:
The bar over any number to the right of a decimal point denotes that the number is recurring. Meaning that if the bar (line) is over the number 3 in 0.3, the number 3 is being repeated infinitely. (0.333333333333333333....) 
These types of decimals are known as repeating or recurring decimals.

Equation at the end of step1: (7x + 18) (4) - 4x = 0 2 STEP2:Equation at the end of step 2 2 • (7x + 18) - 4x = 0 STEP3:STEP4:Pulling out like terms
 4.1     Pull out like factors :
   10x + 36  =   2 • (5x + 18) 
Equation at the end of step4: 2 • (5x + 18) = 0 STEP5:Equations which are never true:
 5.1      Solve :    2   =  0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
 5.2      Solve  :    5x+18 = 0 
 Subtract  18  from both sides of the equation : 
                      5x = -18
Divide both sides of the equation by 5:
                     x = -18/5 = -3.600
 
 
        
             
        
        
        
If 6 of the 13 books are new, then 7 of them are used. The ratio of new (6) to used (7) is
6:7 or 6/7
Ratio of all books (13) to used books (7) is
13:7 or 13/7
