The cost of a $9.85 item that is being discounted 12 percent can be determined by subtracting 12 percent of $9.85 from $9.85. The following equations show that the cost of this item can also be found by taking 88 percent of $9.85. Round your answers to the nearest cent. 9.85 – (0.12 x 9.85) = (1 × 9.85) – (0.12 × 9.85) = (1– 0.12) × 9.85 0.88 x 9.85 %3D Use one of these two methods to compute the discounted cost of each of the following items. a.
