You buy six notebooks and a backpack. The cost of the backpack is $17.90. You pay 6% in sales tax. Your total bill is $30.74. How much does each notebook cost?

Set this up as an equation to start out. We'll call the a notebook n. First you need to subtract the sales tax from the total price...30.74 - (30.74*.06) = 17.9 + 6n Simplify 28.92 = 17.9 + 6n Subtract 17.9 from both sides. 11.02 = 6n Divide both sides by 6 1.8367 = n (so this is the cost of 1 notebook.)

$1.85 per notebook Check: ($1.85)(6)=$11.10 $11.10+$17.90=$29.00 ($29.00)(.06)=$1.74 $29.00+$1.74=$30.74

The cost of each notebook is approximately $1.84 after calculating the total cost before sales tax. This was achieved by determining the total amount paid minus the sales tax and solving the equation for the cost of the notebooks. The final setup showed the notebooks cost around $1.84 each when purchased in a group of six.
