Tipping Etiquette: It is customary in the United States to include a tip when purchasing a meal (or having one delivered). Recommendations for how much of a tip vary depending on who you ask, but the general range is somewhere between 10% on the low end and 20%. Since not everyone is great at calculating in their head, we're going to build a small program to show us the price with either a 10% or 20% tip applied. You will prompt the user to enter the following information:  Total Price of the Meal  Tax Rate (as a decimal value, not percentage)  Delivery Fee You will store these values in appropriate variables, and use them to produce the following intermediate values:  Total Tax (Total Price of the Meal * Tax Rate)  Subtotal (Total Price of the Meal + Delivery Fee)  10% Tip (Subtotal * 10%)  20% Tip (Subtotal * 20%)  Total, 10% Tip (10% Tip + Subtotal + Total Tax)  Total, 20% Tip (20% Tip + Subtotal + Total Tax) You will then print the results to the user.
