Cds are on sale at the local music store for $12.80 each they normally sell for 16 each ann buys three cds for a total of $38.40 what percent discount did she receive

The discount is 20%.

16  x  3 =   $48.00 regular price for 3 CDs

$48.00 - $38.40 =  $9.60

$48.00  x   20%

48  x  .20  =  9.6

Hope this helps. :)
