How many batches of cookies can I make

Question

if I am backing cookies and have 2/4 of a cup of sugar, 2 2/5 cups of flour, 2 1/4 of brown sugar and 3 3/8 cups of water the directions use 0.1125 of a cup of dough to make one cookie and 1 batch should make a total of how many cookies?

Answer 1

(2/4 + 2 2/5 + 2 1/4 +3 3/8) \ .1125 = answer

.5 + 2.4 + 2.25 + 3.37   Divided by .1125 

8.525/ .1125

75.8 cookies

Answer 2

Hmmm.  Pat's answer seems like a reasonable approach to an unreasonable problem. Her math works out - minor typo should be 3.375, no effect on the answer. 

 

Given "Real World" cooking, there's not enough information to answer the question.  The water dissolves the two types of sugar and enters suspension with the flour, so there's no simple way to predict how much dough is created from a certain number of cups of sugars, water and flour.  Also, they don't have a leavening agent or butter, so that's not going to be a very good cookie.  ;) 

 

Where the heck did they gat a number like 0.1125 cups?  That's 9/80ths of a cup, or 9/10ths of an ounce, or 1.8 tablespoons.

 

Real world recipe would use 2 tablespoons, reducing the number of cookies by 10%, and then they'd generalize to "makes 6 dozen cookies."
