Mason spent $15.85 for 3 notebooks and 2 boxes of markers. The boxes of markets cost $3.95 each, and the sales tax was $1.23. Mason also used a coupon for $0.75 off his purchase. If each notebook had the same cost, how much did each cost?

Each notebook is $2.49

Explanation:

So the formula for this particular question is
3x+2($3.95)+$1.23-$0.75=$15.85

Where
3x is equal to how many notebooks were purchased at a certain price x.

2($3.95) is equal to the 2 boxes of markers purchased as $3.95 each.

$1.23 is equal to sales tax for this transaction.

-$0.75 is equal to his coupon that removes 75 cents from the subtotal.
