$84
$160 * 0.30 = $48
$160 - $48 = $112
$112. * 0.25 = $28
$112 - $28 = $84
Use what you know.
Guitar cost =$160 w/ 30% off
30% = 30/100 = 0.30.
30% off means 30% of the price $160 will be taken off so that is why I multiplied 160 by 0.30 (30/100).
30% of 160 is 48 so I subtracted 48 from 160 which equals $112.
With an extra 25% off I repeated the same steps above.
25/100 = 0.25
$112 * 0.25= $28
$112 - $28 = $84
If you need me to break it down more just let me know. I HOPE THIS HELPS
