1. ## consumer

hi, i am in dier need...i am a senior and i have to take an exam for consumer math...this exam depends on me graduating this coming week, i took it today but i failed my teacher agreed to letting me re-take the exam....
the basics are:
selling price
mark up
and mark up rate
dmf

2. The selling price for a desired mark-up percentage is:

$\text{Selling Price} = \text{Total Cost }(1 + \text{Mark-Up Percent})$

The desired mark-up percentage is as follows:

$\text{Mark-Up Percent} = \frac{(\text{Selling Price} - \text{Total Cost})}{\text{Total Cost}}$

If you need any other formulas, I'll be glad to oblige.
