Answer:
Cost per Electricity Unit= $0.61
Cost per Gas Unit= $0.22
Step-by-step explanation:
Suppose,
Cost per Electricity Unit: e
Cost per Gas Unit: g
for the first month condition, equation would be

and for the next month condition, equation would be like

By solving both linear equations simultaneously, we get
e=0.61    and     g=0.22
 
        
             
        
        
        
So if the radius is 2 then the diameter is 4 since the radius is half of diameter. Circumference is 3.14.
3.14× 4 =12.56
        
                    
             
        
        
        
C is not correct
You can call it line m
You can call it PR or QR
