Below is the output for a linear program model in excel

Answer Report:

Objective Cell $($Max$)$

$\backslash$table$[[$Cell$,$Name,Original Value,Final Value$],[$SE$$10$ Total Profit:,,$0,4100]]$

Variable Cells

$\backslash$table$[[$Cell$,$Name,Original Value,Final Value,Integ$],[$$$8$$$10$ # produced Tables,$0,30$ Contin$],[$$$c$$$10,$# produced Chairs,$0,,0$ Contin$]]$

Constraints

Why are the carpentry and the painting and varnish constraints binding?
