Answer:
Each notebook costs $1.25
Step-by-step explanation:
We'd have to add back the $6.00 coupon to the original price which would now be $11.25.
After getting the original price we now have to divide the price by 9, because of the 9 notebooks you've purchased.
Therefore, the price of $11.25 divided by the 9 notebooks would cost 1.25 each.
