Lou Senior took 3 cookies out of the cookie jar and ate them.  Since he didn't get caught by his wife, he went back the next day and took another 3 cookies out of the jar.  But after eating just one of the cookies, he felt guilty about it and put the other two cookies back.  His son, Louie Junior saw that his Dad was eating cookies.  So, Louie Junior took seven cookies out of the jar and hid them in his bedroom for later.  The next morning, Debra, Lou's wife looked into the cookie jar and reacted by accusing her husband of eating half of the cookies out of the cookie jar.  How many cookies remained in the jar?
Lou Sr 3 cookies from the jar, then another three, but then put two back, for a total of 3+3-2=<<3+3-2=4>>4 cookies removed.
Louie Jr took seven more out of the jar, for a total of 4+7=<<4+7=11>>11 cookies removed.
If Debra thought half were gone, then the number of missing cookies would equal the number of cookies that remain, or 11 missing=11 remaining cookies
