Registers:
R1 = Cost
R2 = Price
R3 = Markup
R4 = Margin
Instructions:
The program primary runs on the cost-price-markup calculation,
which belongs to labels A, B, and C, respectively.
Conversions between margin and markup are used between labels
D and E. Gamo recommends that you set
the calculator in FIX 2 mode and press [ f ] (USER) prior to running this
program.
This program is set up to be a solver similar to the HP 12C
and Hewlett Packard other financial calculators.
Examples
It is assumed that FIX 2 is set and USER mode is turned on.
Example 1: (from Gamo)
Cost = 66.46
Price = 105.00
Keystrokes:
66.46 [ A ]
105.00 [ B ]
[ C ], Markup = 57.99
[ C ] [ D ], Margin = 36.70
Example 2:
Cost = 2500.00
Margin = 10.00
2500 [ A ]
10 [ D ]
[ E ] [ C ] [ B ],
Price = 2777.78
Example 3:
Price = 48.75
Markup = 10.00
48.75 [ B ]
10.00 [ C ]
[ A ], Cost = 44.32
Example 4:
Margin/Markup Calculation
Markup = 54.00
54.00 [ E ]
[ D ], Margin = 35.06
