Pricing Calculator for HP Prime

[Gamo]

Lately I try to make this Pricing Calculation program on HP 15C since it got LBL that can assign Price Cost Margin Markup to individual label.

The HP 10 BII+ got this pricing calculator that you just input 2 of the 4 known variables such as if you know Cost and Markup then it will compute for Price and Margin.

Anyone got the idea on how to do this by programming to HP 15C using A B C D
labels just by press 2 known variables like Price (A) Cost (B) Margin (C) Markup (D)
