$16.$ Some analysts complain that spreadsheet models are difficult to resize. You can be the judge of this.

Suppose the current product mix problem is changed so that there is an extra resource, packaging labor

hours, and two additional PC models, $9$ and $10.$ What

additional input data are required? What modifications are necessary in the spreadsheet model $($including range name changes$)?$ Make up values for any extra required input data and incorporate these into a modified spreadsheet model. Then optimize with Solver.

Do you conclude that it is casy to resize a spreadsheet

model? $($By the way, it tums out that algebraie models are typically much easier to resize$).$
