Casey has a job doing valet parking. Casey makes an hourly rate of \( \$ 4.55 \) per hour plus tips. Last week Casey worked 26 hours and made \( \$ 898.55 \). How much in tips did Casey earn last week? a. \( \$ 34.56 \) b. \( \$ 118.30 \) c. \( \$ 157.25 \) d. \( \$ 780.25 \) Please select the best answer from the choices provided A B

To find out how much in tips Casey earned last week, we first need to calculate the total earnings from the hourly wage and then subtract that from the total earnings to find the tips. Casey's hourly wage is \( \$ 4.55 \). If Casey worked 26 hours, the total earnings from the hourly rate would be: \( 26 \text{ hours} \times \$ 4.55/\text{hour} = \$ 118.30 \). Now, subtract the earnings from the total earnings to find the tips: \( \$ 898.55 - \$ 118.30 = \$ 780.25 \). So, Casey earned \( \$ 780.25 \) in tips last week. The correct answer is option d. In case you’re curious, tipping has a rich tradition in service industries, originally arising in Europe during the Middle Ages. Customers would give a small amount of money "to ensure promptness"—abbreviated to T.I.P. If you're ever uncertain about how much to tip, consider the service quality and local customs. Generally, tipping around 15-20% of the total bill is considered acceptable in restaurants. For valet services like Casey's, a few dollars for great service or a larger tip if you have a luxury vehicle or during busy times can be a nice gesture!
