To find the cost of each item after applying a 15% discount, we need to calculate 15% of the original price and then subtract that amount from the original price.<br /><br />Let's calculate the discounted price for each item:<br /><br />a) Pencil:<br />Original price: $200<br />Discount: 15%<br />Discount amount: 15% of $200 = 0.15 * $200 = $30<br />Discounted price: $200 - $30 = $170<br /><br />b) Ruler:<br />Original price: $800<br />Discount: 15%<br />Discount amount: 15% of $800 = 0.15 * $800 = $120<br />Discounted price: $800 - $120 = $680<br /><br />c) Textbook:<br />Original price: $3500<br />Discount: 15%<br />Discount amount: 15% of $3500 = 0.15 * $3500 = $525<br />Discounted price: $3500 - $525 = $2975<br /><br />Therefore, the discounted prices for the items are:<br />a) Pencil: $170<br />b) Ruler: $680<br />c) Textbook: $2975
