100% = 1.00
45% = .45
100% + 45% = 1.45
1.45 * cost = sale price = 94.25
cost = 94.25/1.45
cost = $65.00
a marked price on an mp3 player is $15000.Calculate the price of the item after a 12% discount given.

Marked price on mp3 player =$15000
Discount % =12%
discount =12/100 multiply by $ 15000
$180
new price=$15000-$180 =$14820
answer:$14820
