Question 1210642
.
You have $39 to spend at the music store. Each cassette tape costs $5 and each CD costs $11. 
Write a linear inequality that represents this situation. Let x represent the number of tapes and y the number of CDs.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



<pre>
Write inequalities as you read the problem


    5x + 11y <= 39,

    x >= 0,  y >= 0.



Actually, there are 3 (three) inequalities, describing the situation, not one.


Plus an additional condition that x and y are integer numbers.
