- In the Barney-Jones investment model, we ran invest-ments across columns and years down rows. Many financial analysts seem to prefer the opposite. Modify thespreadsheet model so that years go across columns andinvestments go down rows. Run Solver to ensure thatyour modified model is correct. (There are two possibleways to do this, and you can experiment to see whichyou prefer. First, you could basically start over on a blankworksheet. Second, you could use Excel’s TRANSPOSEfunction on the final version of the model.)hHELPPPP WITH THIS QUESTIONCan you assist with these please? Build a CKY table to parse each sentence below.
