Enter the numbers in the appropriate cells of ranges B4:H6 in the Excel spreadsheet to solve this problem based on the following formulation.
Let $\quad w _ { i } =$ werght as5igned to dutput $j , j = 1 , \ldots , 4$
$\mathbf { v } _ { i } =$ waight as5igned to ingut $i , i = 1 , \ldots , 3$

MAX: $\left. \left. \quad 82.7 w _ { 1 } + 175 .\right] w _ { 2 } + 65.0 w _ { 3 } + 83 .\right] w _ { 4 }$
Subject to:
