For A well I can't do a graph ,but to do it you would start at 50 going up 25 each week 
For B it would be 300 because 25×10=250 plus the 50 from his grandmother he would have 300
        
             
        
        
        
336 divided by 75 which equals 4.48
        
             
        
        
        
So hmm notice the picture below
that's (0, -3)
now, keep in mind, adjacent is 0, opposite is -3, and hypotenuse, or radius, is 3
and recall  
 
 
        
        
        
Answer:265.25
Step-by-step explanation:
Given
Volume of box
height is 3 times the width
let height, length and breadth be H, L & B


4=B^2\times L[/tex]

Cost of side walls $ 
Cost of base $ 
Cost of side walls
Cost of base 
Total cost 


differentiate C w.r.t B to get minimum cost




L=2.19 m
C=$ 265.25
