Problem: the price of an item is discounted 4 percent on day 1 of a sale . on day 2 , the item is discounted another 4 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 4 % discount = 96 price in day 2 after 4 % discount = 92.16 price in day 3 after 10 % discount = 82.94 so , price in day 3 as percentage of the sale price on day 1 will be = 82.94 / 96 * 100 = > 86.4 % answer will definitely be ( d )"
annotated_formula: add(multiply(divide(divide(10, const_100), subtract(1, divide(1, 4))), const_100), 2)
