i'm thinkin this is geek zone, and altho i guess it's for computer n technology questions, i think math goes hand in hand.
if i want to make a percentage on something, how do i figure it out
example, i buy something at cost for $5, i want to make 30% on that $5. how do i figure it out

You want 130% of $5.00 (your original $5.00 + 30%).
1.3 x 5 = 6.5
You would sell it for $6.50
Or:
(.3 x 5) + 5 = 6.5 (same $6.50)

Or:
(.3 x 5) + 5 = 6.5 (same $6.50)
but that comes out to 23% profit
using the profit formula
(sell - cost)/cost

(sell - cost)/cost
(6.50 - 5.00)/5.00 = .3
which is 30% profit

Another way:
$5.00 x 30% = $1.50
$5.00 + $1.50 = $6.50

One more way:
(amount * percentage) / 100 = profit
amount + profit = total
(5 * 30) / 100 = 1.5
5 + 1.5 = 6.5

what are you selling for a thirty percent profit, its a very slim margin on a low ticket item unless you know that you can sell a high volume of this product.
