(Express the answer as an integer)
For price and discount problems, first decide the order of operations: apply percentage discounts to the original price, then apply any flat dollar coupons to the new price. Convert percentages to decimals (like 15% → 0.15 or 1 − 0.15 = 0.85) and use multiplication for the percent step and subtraction for the coupon step. Writing a single expression, such as original_price*(1 − percent) − coupon, helps you move quickly and avoid forgetting any discount. Аnіko - Freе ЅАТ Рrер
