If each notebook cost x, then
3x + 2*3.95 + 1.23 - 0.75 = 15.85
Now just solve for x.
3x + 2*3.95 + 1.23 - 0.75 = 15.85
Now just solve for x.
First, let's calculate the cost of the markers. Since the cost of each box of markers is $3.95 and Mason bought 2 boxes, the total cost of the markers is 2 ร $3.95 = $7.90.
Next, let's calculate the total amount spent before using the coupon. The total amount spent before using the coupon is $15.85 + $1.23 (sales tax) = $17.08.
Now, let's subtract the cost of the markers ($7.90) and the coupon amount ($0.75) from the total amount spent before using the coupon to find the cost of the notebooks. The cost of the notebooks is $17.08 - $7.90 - $0.75 = $8.43.
Since there were 3 notebooks, we can divide the cost of the notebooks by the number of notebooks to find the cost of each notebook. The cost of each notebook is $8.43 รท 3 = $2.81.
Therefore, each notebook costs $2.81.
