Hi, vodkaga: Here's the formula I came up with: Let C be the cost of a country in dollars, with: A = AIDs population D = purchasing power in dollars P = total population C = 0.000722 * ( D*(P  2.62*A)  $12,000*A ) Note that as the units of D are dollars/person and other inputs A,P are "pure" numbers or population counts, the units of the right hand side expression are consistent. For the three countries that you have cost "data" for, the results are in good agreement with the given dollar amounts: Country Price (given) Price (formula) ========== ============== =============== Swaziland $ 800,000 $ 801,133.80 Mozambique $1,000,000 $1,008,826.05 Botswana $2,000,000 $2,001,626.95 The three parameters in my formula were rounded a bit, for simplicity and to avoid a pretense of greater accuracy than the data allows. Of course I could exactly match the three results (using three parameters), but this would not have much predictive value for other countries, so I made the answer simpler to keep this in perspective. regards, mathtalkga
