Question

At a particular music store, CDs are on sale at $12.00 for the first one purchased and $9.00 for each additional disc purchased. Maria spends $84.00 on CDs.How many CDs has Maria purchased ?

A- 6
B- 7
C- 8
D-9

Answer 1

D. 9

Explanation:

$84 - $12 = $72

$72 divided by $9 = 8

8 CDs + 1 CD = 9 CDs

Answer 2

84.00 - 12.00 = 72.00 (1st cd is $12.00)
72 ÷ 9 = 8 (The rest of the cds are $9.00)
1+8=9

Maria purchased a total of 9.
