## Algebra and Trigonometry 10th Edition

Therefore the new production levels are: $\begin{bmatrix} 110 & 99 & 77 & 33\\ 44 & 22 & 66 & 66\\ \end{bmatrix}$
Multiply the matrix by a scalar of 1.1 to represent the 10% increase. $\begin{bmatrix} 100(1.1) & 90(1.1) & 70(1.1) & 30(1.1)\\ 40(1.1) & 20(1.1) & 60(1.1) & 60(1.1)\\ \end{bmatrix}$ = $\begin{bmatrix} 110 & 99 & 77 & 33\\ 44 & 22 & 66 & 66\\ \end{bmatrix}$ Therefore, the new production levels are: $\begin{bmatrix} 110 & 99 & 77 & 33\\ 44 & 22 & 66 & 66\\ \end{bmatrix}$
