Answer:
5 drinks
Step-by-step explanation:
If the drinks cost $2.32 and you have $13 you can divide 13 by 2.32
13/2.32+ 5.6034...
You cannot buy a partal drink so you look at only the whole number which is 5.
 
        
                    
             
        
        
        
10*3=30
30*3=90
90*3=270
270*3=810
or
10*3^1=30
10*3^2=90
10*3^3=270
10*3^4=810
the next two terms of this sequence are 270 and 810.
