Question 877537
x = # of tapes
y = # of CDs



Buying x tapes at $10 a tape, costs 10x dollars
Buying y CDs at $12 a CD, costs 10y dollars
Total cost: 10x+12y dollars


You have $44 to spend, so this is the most you can spend. This is the upper limit or ceiling. 


That means 


{{{Total_Cost <= 44}}}


{{{10x+12y <= 44}}}


=======================================================


So the inequality is {{{10x+12y <= 44}}}
