Question 233827
fred bought 3 shirts, each at the same price, and received less than $12.00 in change from a $50 bill. What is the minimum cost of one shirt?
-------------------------------------------
Let minimum cost of one shirt is  "x".
----------------
50-remainder = 3x
------------------------- 
If remainder < 12, 38 <= 3x <= 50
Then (38/3) < = x <= 50/3
12 2/3 <= x <= 16 2/3
--------------------------------
Minimum cost is $12.67 
===================================
