Answer:
111.65
Step-by-step explanation:
$15.25 x 3 = $45.75
$32.95 x 2 = $65.9
Total: $111.65
 
        
                    
             
        
        
        
The rate of change in z at (4,9) as we change x but hold y fixed is =
3/[2sqrt(3x+2y)] put x = 4 , y = 9 = 3/[2sqrt(12+18) = 3/[2sqrt(30)] The
rate of change in z at (4,9) as we change y but hold x fixed is =
1/sqrt(3x+2y) put x = 4, y =9 = 1/sqrt(30)
