    how to calculate prices per foot square for group of lands

    Hi,

    i am looking for a formula to solve the following problem
    i have about 60 lands, measured 3000 f2 to 6000 f2
    i need a formula to calculate to price per foot square vary from $22 to $25
    i want to start with $22 /f2 for 6000 f2 to $25 /f2 for 3000 f2
    so the 4500 f2 should be $23.5 and so on

    i hope i make it clear

    thanks in advance

    Re: how to calculate prices per foot square for group of lands

    Hey sitri.

    Do you want the prices to be $22 for 6000, $25 for 3000 and all appropriate numbers in between?

    If so we use what is called linear interpolation which gives us the result:

    Price_Per_Square_Foot = mx + b where m = (25-22)/(3000-6000) = -1/1000 and b is found by calculating:

    22 = -1/1000*6000 + b
    25 = -1/1000*3000 + b

    or

    22 = -6 + b
    25 = -3 + b or b = 28.

    This means we now have a formula to calculate the price per square foot which is

    Price = -1/1000*(total_square_feet) + 28 where total_square_feet is in between 3000 and 6000 inclusive.
    Thanks from sitri
