2. We have acquired a recipe for the world famous Mrs. Hansberry's Peanut Butter Cookies. Unfortunately, it is a recipe for commercial use and needs to be modified for our use. Here is a list of the ingredients with their quantities:

10 gal butter or margarine
10 gal granulated sugar
320 eggs
25 gal sifted flour
salt is 1/3 the amount of soda

10 gal peanut butter
10 gal brown sugar
31/3 c vanilla extract
5c soda

3 t (teaspoons) = 1T (tablespoon)
4 qt = 1 gal (gallon)
8 qt = 1 peck

4 C = 1 qt (quart)
2 C = 1 pt. (pint)
1 C = 8 fl. oz. (fluid ounces)

16 T = 1 C (cup)
4 pecks = 1 bushel

This makes 128 packages with two rows of five cookies stacked three high. If you are going to make four dozen cookies, how many teaspoons of soda will you need?
