Regardless of how you do this calculation (even if you do it longhand), you are using an equation:
Next Forecast = Old Forecast + Change in Old Forecast
=Old Forecast + (Projected Percentage Changes xOld Forecast)
or:
NEXT = OLD + ((A% + B% + C%) ⎟ 100 x OLD)
Using the SOLVE and ALPHAbetic menus, you can type in this equation as
<HX:8E9A)L16)J6)76TD#((BE9A"
and then automatically create this menu ―which contains all the variables’ labels―by pressing I E:*
Each menu label represents a variable. You can use them to store and calculate values the same way you use other menus and their
Entering a Solver Equation. To type this equation, you must use the ALPHA menu. If you are not familiar with the ALPHAbetic menu, refer to “ Typing Words and Characters ” on page 30.

*Because the Solver uses arithmetic priority (B, D before ), /), a second set of parentheses (before A% and after the second OLD) is not necessary. See “Order of Calculations,” page 165.
