SITE-A teams: Lesson 7

 

Gratuity on service at a restaurant is usually 15% of the cost of the meal before the tax is added to the bill.

Can you develop a table that displays what the amount of gratuity should be for meals costing between $20 and $200 with dollar increments of 10?

Let X represent the cost of the meal before the tax is added to the bill, and let Y be the amount of gratuity that should be left for the service provided.

Turn on the CASIO fx7400G.
