Expert Solution
Step 1 Introduction:

Here, I would determine the number of hours for plant A and the number of hours for plant B, 

Let me consider, for order 1, The number of hours for plant A is X1, the number of hours for Plant B is Y1,

For order 2, the number of hours for Plant A is X2, the number of hours for Plant B is Y2,

For order 3, the number of hours for Plant A is X3, the number of hours for Plant B is Y3,

Here, I would set up the linear system, then solve this problem, 

 

For order 1, 

5×X1+10×Y1=9105×X1+4×Y1=436

 

For order 2, 

5×X2+10×Y2=9205×X2+4×Y2=434

For order 3, 

5×X3+10×Y3=14805×X3+4×Y3=1138

Now, I would solve this system below,
