In the market maze, where numbers blaze
Cost basis is a torch wield with graces
Dollars here, dollars there, costs turn to prices
Mark it up with care, every case has its own space
Percentage wise, markup magic, so precise
On variable costs, it's a roll of dice
Margin's melody, adding spice to the price
Percentage of total, in the profit slice
When demand swings high, price tags fly
When it dips low, high tags don't flow
A dynamic dance, prices prance
Variable rhythm, in a market schism
Competition's boon plays another tune
Product homogeneity causes price elasticity
Cost consideration is this markets iteration
Under skimming skies, prices rise, for
Desire's fire, reaching the highest buyer
Penetration's plot, stealthiness is bought
Undercut the prize for market share to rise
From peak to penetration, it's a symphony
Of figures, digits, and the currency melody
Markup, margin, and demand's destiny
In this commerce, we find our strategy
