What size spoon?
3.5.1 Spoon volume
1 tea spoon (the smallest spoon) = 4.5 - 5 mL (0.2 fl oz)
1 dessert spoon (the spoon you eat with) = 10 mL
1 table spoon (tblspn) (spoon to serve with, the biggest spoon): 15 - 20 mL (0.5 fl oz)

Milliliter and fluid ounces measure volume (and, in the case of the second unit you use, only liquid volume, which obviously doesn't apply to baking powder.). The original measurement is in weight. Unless you are making some unstated (and very convenient) assumptions regarding density, I'm afraid your equalities would appear to be unjustifiable.Denis said:
To the original poster: Please provide the necessary conversion factors. When you reply, please include a clear listing of everything you have tried so far. Thank you!

I'm afraid that according to this website: http://www.ilpi.com/msds/ref/volumeunits.html, stapel is unfortunately right - fl. oz and oz are not interchangeable. Therefore I would go ahead and assume that the problem is giving you a quantity in fluid ounces, otherwise, you wouldn't get anywhere anytime soon. Having said that, the cost of one ounce (here one fluid ounce) would be approximately 25 cents. From here, you need to convert ounces into teaspoons. The conversion factor for this is: 1 fluid ounce is 2 tablespoons, then 1 teaspoon is (1/3) tablespoon.
So, there are 6 teaspoons in a fluid ounce which means that it costs 25 cents for 6 teaspoons of baking powder. However, you are looking for the cost of 3 teaspoons, so simply divide that cost by 2 and you'll get the cost of 3 teaspoons of baking powder:
