Question 1063862
.
Suppose two eggs with bacon cost $2.70. One egg with bacon costs $1.80. At these rates what will bacon alone cost
~~~~~~~~~~~~~~~~~~~~~~


Nice problem !!    Thanks for posting it !   It has nice solution,  too.


<pre>
Two eggs with bacon cost $2.70.

One egg with bacon costs $1.80.


HENCE (!), one egg costs exactly $2.70 - $1.80 = $0.90.   Agree ?


Now only one step remains to reveal that the bacon itself costs $1.80 - $0.90 = $0.90.


<U>Answer</U>. The bacon alone costs $0.90.

Solved (!)



It is how the Elimination method works 

I explained it to you here without using equations.


I used the words only (!!).
