<PRE><B>Question 1063210</B>
A dozen cookies and a loaf of bread cost $6.70. Half a dozen cookies and 2loaves of bread cost $6.05. A loaf of bread costs? 
---------------------
12c + b = 670 cents
6c + 2b = 605 cents
--------------------------
Modify for elimination:
12c + b = 670
12c + 4b = 1210
------------------
3b = 540
------
b = $1.80
----
Loaf of bread cost:: $1.80
