85 x 3 = 255
 first 2 test grades were 81 and 86: 
81 + 86 = 167
Need to find the 3rd to have exact average 85:
255 - 167 = 88
So her 3rd test needs to make 88 to make average of 85
Double check: 81 + 86 + 88 =  255 = 85 + 85 + 85
        
             
        
        
        
It's C)12 squared because you have to look outside of the box
