Firstly we need to find out how much is 10% from $1,500:
$1500 * 10% =
= 1500 * 10/100 =
= 1500 * 1/10 =
= 1500 / 10 =
= 150
So the price after 10% discount would be $1,500 - $150 = $1,350. Now if you have 30% coupon, we need to find out how much is 30% from $1,350:
$1350 * 30% =
= 1350 * 30/100 =
= 1350 * 3/10 =
= 4050 / 10 =
= 405
It means that you'll pay for the discounted product $1,350 - $405 = $945.
