Answer:
... costs establish the base for her prices.
Explanation:
Usually most small businesses use the cost-based pricing method. This pricing method uses mark-up pricing, e.g. your total costs are $10 per unit and your mark-up is 25%, therefore your final selling price will be $12.50.
This pricing method is the most simple and practical method especially for small businesses although large corporations also use it as well as most contractors, both private and public.
