A parent finds a staples graphing calculator ti 84 listed for $139.99 during a promotion. They have a 15% Staples coupon. They buy a $10 protective case. With a 6% tax rate, the calculation is: (($139.99 * 0.85) + $10) * 1.06 = $136.73. This shows how discounts significantly offset the cost of accessories.
