<PRE><B>Question 1046876</B>
 On Tuesday KAli bought four hats. On Wednesday half of all the hats that she had were destroyed. On Thursday there were only 13 left. How many did she have on Monday? 
=====
Monday:: x hats
Tuesday:: x+4 hats
Wednesday:: (x+4)/2 hats
---
Equation: (x+4)/2 = 13
x+4 = 26
x = 22 (# of hats on monday)
