Use a two$-$way SolverTable to investigate the effect on total cost of two simultaneous changes. The first change is to allow the ratio of overtime to regular$-$time production cost $($currently $$16/$$$8=2)$ to decrease from $20\%$ to $80\%$ in increments of $20\%,$ while keeping the regular time cost at $$8.$ The second change is to allow the production capacity each month $($currently $2,500)$ to decrease by $10\%$ to $50\%$ in increments of $10\%.$ The idea here is that less regular$-$time capacity is available, but overtime becomes relatively cheaper. Is the net effect on total cost positive or negative?
