I would first like to praise you for showing your work...thanks! Now, lets figure out how much we are getting off of this product. 15 + 10 is 25 so that's 25% off. We are paying 75% so we multiply .75 by 55 and get $41.25. Now that we know the price with the discount, that's pay with tax!
$41.25 times 1.06 comes out to 43.725 so lets round to $43.73
The total cost for the product would be $43.73 and $41.25 is getting taxed. I hope this helps.
