The total cost for one can is: $25.41.
__________________________________________________
Let us assume that we want to know the total cost of ONE CAN.
_____________________________________________
To calculate our answer:
_______________________________
$ 23.97 + [ (6/100) * 23.97)] = Our answer, in dollars.
__________________________________________
Note: "6%" = 6/100 = 0.06
_______________________
Rewrite as:
____________
$ 23.97 + [ (6/100) * 23.97)]  = our answer, in dollars; 
_____________________________________________
    $ 23.97 + (0.06 * 23.97)
            =    $ 23.97 + 1.4382
            =      $ 25.4082 ; Round to decimal places, to get:
                                         <span>→ $ 25.41

Answer:
4x cm.
Step-by-step explanation:
Suares have to have all 4 sides equal. The area of the rectangle (2x8) is 16.
16/4 = 4, so the square has sides of 4cm each to equal an are of 16. (4x4=16)
 
        
             
        
        
        
Do cross multiply or butterfly.  
For example first one.
18/x=6/10  So cross multiply  18×10 =6x
180=6x
Divide both sides by 6 to get x alone
180÷6=30
So x =30  Do the same to rest
 
        
             
        
        
        
Step-by-step explanation:
 F= 9/5(C + 32)
5/9 F = C + 32
C = 5/9 F - 32
