(11C) COST AND PRICE COMPUTATIONS

[Gamo]

This program is adapted from the HP-67/97 Users' Library Solutions "Marketing/Sales Page 51

According to this book this program is called " Cost and Price Computations "

Program Description, Equations, Variables

Sales work often involves calculating the unknown
amongst the interrelated terms margin, markup, selling price, and cost. Margin is
defined as 100 x (selling price - cost) ÷ selling price. Markup is 100 x (selling price - cost) ÷ cost.
There are numerous equations which evolve from the interrelation of these terms.
This program solves for any of the four variables when two of the other variables are known.

--------------------------------------------------------------
Keys Variables

[A] Selling Price // [A] and [B] use for either as input and output
[B] Cost
[C] Margin // [C] and [D] use for input only
[D] Markup

[GSB] 7 // Output Answer for Margin
[GSB] 8 // Output Answer for Markup

--------------------------------------------------------------

Example: FIX 2 [USER]

a) If the margin is 20% and cost is $160, what is the selling price?

20 [C] display 0.20
160 [B] display 160.00
[A] [R/S] display answer for Cost = 200.00

b) If the margin is 30% what markup would this be?

30 [C] display 0.30
[GSB] 8 display 42.86

c) If the Price is $50 and Markup is 25% What is the Cost and Margin?

50 [A] display 50.00
25 [D] display 0.25

[B] [R/S] display answer Cost = 40.00
[GSB] 7 display answer Margin = 20.00
