You can put this solution on YOUR website!
Start with 10%, as this is easy! 10% of $15.00 is $1.50.
As 40 is 10 x 4, you need to multiply $1.50 by 4 to get 40%:
1.5 x 4 = 6, therefore 40% of 15 = $6
Now that you know how much 40% is, you can use it to work out the discounted price of the item.
$15 - $6 = $9
Therefore, a $15 item with 40% off is $9.
