Answer:
They sold 67.50 in total
Step-by-step explanation:
If each of them sold 15 boxes for 2.25 then both of them got 33.75 each then you add it and that gives you 67.50
 
        
             
        
        
        
The formula is d=C/π.
The diameter is 2 times the radius
The formula for the circumference using the radius is 2πr.
in order to do this backwards, we would have to do 16÷2÷π, but we're not looking for the radius.
Therefore, we take out the ÷2 part, which would be 16÷π
16 is the circumference
16÷π=d
d=C÷π
 
        
                    
             
        
        
        
I'm going to need more information before I can answer.
        
             
        
        
        
Answer:
3 coins / 7 bills
Step-by-step explanation:
42c/98b --(:2)--> 21c/49b --(:7)--> 3c/7b
OR
42c/98b ---( : 14 = (2*7))--> 3c/7b
