Write a complete C program that prints a receipt at a restaurant. 
The program must ask waiter to enter the amount (in $) and then 
calculate the sales tax (assuming a tax rate of 7%). The program 
must then print a receipt similar to the one shown below and suggest 
three possible tips based on the amount before tax (15%, 20%, 25%).

SAMPLE RUN:

Enter amount: 45

 Amount  $45.00
 Tax     $ 3.15
 Tip     ______
 ______________
 TOTAL   ______


 15% tip = $ 6.75
 20% tip = $ 9.00
 25% tip = $11.25

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
	
#define TAX_RATE 0.07 // 7% tax

int main()
{
	float amount;
	printf("Enter amount: ");
	scanf("%f", &amount);

	float tax = amount * TAX_RATE;
	
	float tip15 = amount*0.15;
	float tip20 = amount*0.20;
	float tip25 = amount*0.25;
		
	printf("\n");
	printf(" Amount  $%5.2f\n", amount);
	printf(" Tax     $%5.2f\n", tax);
	printf(" Tip     ______\n");
	printf(" ______________\n");
	printf(" TOTAL   ______\n\n\n");
	     	
	printf(" 15%% tip = $%5.2f\n", tip15);
	printf(" 20%% tip = $%5.2f\n", tip20);
	printf(" 25%% tip = $%5.2f\n", tip25);
	
	system("pause");
