Answer:
Maria purchased total 8 CDs.
Step-by-step explanation:
At a particular music store, CDs are on sale at $13.00 for the first one purchased and $10.00 for each additional disc purchased.
Maria spends = $83.00
She purchased her first CD for = $13.00
Now balance of her charge = 83.00 - 13.00 = $70.00
other CDs are purchased for $10.00
Therefore, 70.00 ÷ 10.00 = 7 CDs
Total CDs = 7 + 1 = 8 CDs
Maria purchased total 8 CDs.
