The cost of making 10 pounds of homemade birdseed can vary based on the prices of the individual ingredients and where they are purchased. However, if we consider the ingredients mentioned in the context, we can estimate the cost.

Black oil sunflower, which are a key ingredient, can range from $0.50 to $0.70 per pound when purchased in bulk. Peanuts, another important ingredient, might cost around $1.50 to $2.00 per pound in bulk. Cracked corn can vary from $0.20 to $0.40 per pound, and white millet can range from $0.40 to $0.60 per pound.

Considering these estimates, and using the lower end of the price range for each ingredient for a more conservative estimate, the cost of making 10 pounds of homemade birdseed could be:

(2 pounds of black oil sunflower seeds at $0.50 pound) + (2 pounds of peanuts at $1.50 per pound) + (3 pounds of cracked corn at $0.20 per pound) + (3 pounds of white millet at $0.40 per pound) = Total Cost

(2 x $0.50) + (2 x $1.) + (3 x $0.20) + (3 x $0.40) = Total Cost

$1.00 + $3.00 + $0.60 + $1.20 = Total Cost

$5.80 = Total Cost

So, based on these estimates, it might approximately $5.80 to make 10 pounds of homemade birdseed using the specified ingredients.
