To find the amount (A) to leave the waiter at a restaurant, one must calculate the gratuity and add it to the cost (c) of the meal. Will generally leaves about 15% of the cost as a gratuity. Hence, A = c + .15c. Find another formula that would accomplish the same result by a one-step method rather than a two-step method.
