Multiply the amount of the notebooks which is 3, by the cost of the notebook, which is $15.85. that is $47.55.
to find how much it costs with the coupon, do the notebook cost and subtract that by 0.75
$47.55 - 0.75 = $46.8
Sorry my bad, i m not good in maths.
Yes it is already simplified because there is nothing else that you are able to do to it.
