Question 928505
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.
