Complete the table below. Number of hours for plant A Number of hours for plant B Orders 2 3

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, 

$$\begin{gathered} 5\times X_1+10\times Y_1=910 \\ 5\times X_1+4\times Y_1=436 \end{gathered}$$

For order 2, 

$$\begin{gathered} 5\times X_2+10\times Y_2=920 \\ 5\times X_2+4\times Y_2=434 \end{gathered}$$

For order 3, 

$$\begin{gathered} 5\times X_3+10\times Y_3=1480 \\ 5\times X_3+4\times Y_3=1138 \end{gathered}$$

Now, I would solve this system below,
