Problems 1 and 2 require the use of Excel's "Solver" add-in. This may not be immediately available on your installation of Excel. To get to "Solver", you want to click on "Add-Ins" under in the "Developer" tab (or sometimes "Add-Ins" appears as a tab of its own). In "Add-Ins", click the box to enable the "Solver Add-in". "Solver" should then appear under the "Data" tab (probably on the far right). Alternatively you may be able to click on the Solver add-in through the sequence "File" "Options" "Add-ins", then at the bottom, for Manage: Excel Add-ins, click "Go". There you can click on "Solver" and "Ok".
