Need a Clever mind for simple equation

[shaun2k]

Hi guys, i thought i'd hit you up to see if you can help me on your very useful forum..

basically I'm an artist who is making a website and i'm currently working out my pricing..

Ive come up with a basic system to price my work on Density of work per area 2

What i need to do is write the following in a clever way..

example:

Size of canvas (in this case A1 being 775 square inches)

i spend on average 80 hrs per 6" by 6" squared.

6"x 6" = 36" squared... 80 hrs divided by 36 equals 2hr 22 mins per 1 inch squared

that would be what i call maximum density that i can draw..(density being explained like this) 100% density would the greatest and 10% density would be the lowest (for example 10 times bigger than 100%)

So at 2.22 hrs per inch a A1 drawing at 100% density would take me 1720 hrs in total

if i then divide that by 100 and times it by the density% for example 80% it will give me a corrected time in hrs at 80% in this case 1376hrs

my rate is 7ph and i work 10 hrs a day the above would take me 137.6 days and cost £9632 respectively.

in my ****** maths brain i want to write this as intelligently as possible for a header on my site..

something like this

S = Size
T= Time
D=Density
R=rate
P= price
can one of you guys come up with a decent formula for it that looks pretty if its possible


many thanks in advance

\(\displaystyle S^2 \ \div \ S\sqrt{T^2} \ \div \ 100 \times D \times R \ = \ P\)

\(\displaystyle S \ \div \ S\sqrt{TS^2} \ \div \ 100 \times D \times R \ = \ P\)


Those are not equivalent equations. \(\displaystyle \ \ \ S^2 \ \div \ S\sqrt{T^2} \ \ne \ S \ \div \ S\sqrt{TS^2} \)


Did you intend them to be?
