It can't solve all 12 mathematically possible input-output scenarios without doing a required entry-solve sequence ("Part 1", "Part 2") and finding intermediate values that are sometimes unnecessary. The HP 200LX HP CALC Solver solution given 3/27/21 converts from 15% Markup to 13.04% Margin directly (no need for Cost or Price at all), or any other mathematically possible from-to situation: Enter Markup and Cost, Solve for Price (and you get Margin too); Enter Markup and Cost, Solve for Margin (and you get Price too); ... 12 scenarios total. All HP calculators could have done this, but none do so. |
