Option A is correct.
Put the values of x in 3^x and you will get the answer corresponding to option A
        
                    
             
        
        
        
3x+40=100 
subtract 40 from both sides
3x= 60
divide by 3 
x=20 
each Sweater cost 20
        
             
        
        
        
A variable next to any number means to multiply, so we would do the inverse operation -- We would divide 0.48 by 0.6, which is 0.8. Therefore, W=0.48. To check your work, multiply 0.6 by 0.8, and what do you know? It's 0.48! :)
        
                    
             
        
        
        
The total cost would  be:
$20 = two people- 2*20=40$
20 = guest
20*20=
400 would be the cost
