Problem: the price of an item is discounted 6 percent on day 1 of a sale . on day 2 , the item is discounted another 6 percent , and on day 3 , it is discounted an additional 10 percent . the price of the item on day 3 is what percentage of the sale price on day 1 ?
Rationale: "let initial price be 100 price in day 1 after 6 % discount = 94 price in day 2 after 6 % discount = 88.36 price in day 3 after 10 % discount = 79.52 so , price in day 3 as percentage of the sale price on day 1 will be = 79.52 / / 94 * 100 = > 84.6 % answer will definitely be ( b )"
annotated_formula: add(multiply(divide(divide(10, const_100), subtract(1, divide(1, 6))), const_100), 2)
