If I spent $15.85 for three notebooks and 2 boxes of markers the boxes of markers cost 3.95 each and the tax is 1.23 and I have a coupon for 0.75 how much did each notbook cost

15.85 + .75 = 3n + 2(3.95) + 1.23

idk

To find out how much each notebook cost, we need to first calculate the total cost of the markers and tax, and then subtract it from the total amount spent.

The cost of the markers can be calculated by multiplying the price of each box by the number of boxes:
2 boxes of markers * $3.95 per box = $7.90

The total cost including tax is calculated by adding the cost of the markers and the tax:
$7.90 + $1.23 = $9.13

To find the cost of the notebooks, we subtract the total cost of the markers and tax from the total amount spent:
$15.85 - $9.13 = $6.72

Since we bought three notebooks, we divide the total cost of the notebooks by the number of notebooks:
$6.72 ÷ 3 notebooks = $2.24

Therefore, each notebook costs $2.24.
