Answer:
Maria purchased 9 CDs
Step-by-step explanation:
Maria spends $84.00 on CDs. The first CD is $12, the rest $9
As the CD have different price , first we have to discount the price of the first one, and then we divide the rest by $9
Price First CD = $12 ,
We buy the first , so we get the rest of money 84-12=72
Price Rest =$9 , with the money that left , we can buy 72/9= 8
Total= 1 +8 =9
