Question

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?

Answer 1

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.
