Answer:
Each pendant cost $3.30
Step-by-step explanation:
You would subtract $13.20 from $26.20  and get $13.20. You take $13.20 and divide it by 4. You would get $3.30.
 
        
             
        
        
        
38 centimeters = 0.38 meters 
        
             
        
        
        
In order to solve for a, we must isolate it. To do this, we should add c to both sides, making a the only term on the left.
Final answer: a=c+d-r
