Senior Member Joined: Jan 2017 From: US Posts: 112 Thanks: 6  Write a System of Inequalities for this Problem..? A music store is selling CDs for either $10 or $15. A customer wants to spend between $30 and $60 on the CDs. Write the system of inequalities that represents this situation and graph its solution region. Could anyone point me in the right direction with this? I really have no clue where to start. Any help would be appreciated! Thanks in advance!

the customer buys $m$ cds at $10$ and $n$ cds at $15$ they thus spend a total of $10m + 15n$ write the two inequalities that compare this to the amount the customer wants to spend.
