Answer:  6
Step-by-step explanation:
y = mx + b, where b is the y-intercept, in this case, y-intercept is 6. 
 
        
             
        
        
        
A=3B
4.35A+5.40B=780.95
Substitute 3B into A for the second equation:
4.35(3B)+5.40B=780.90
13.05B+5.40B=780.90
18.45B=780.90
B=42.33
Plug into equation 1:
A=3B
A=3(42.33)
A=126.98
