Hi guys, ok so I'm trying to figure this thing with functions out and I've been sitting here for seriously 6 hours with half of it done. I am so confused, please help! The program is to track the amount and price of raffle tickets sold, and then add to a grand total. The price per raffle ticket has to be equal to or greater than $5.00, amount of tickets has to be equal to or greater than 0.

I've planned the program out to hopefully look like this at the end--

WELCOME TO THE RAFFLE!

Enter price per raffle ticket (must be at least $5.00):

Enter number of raffle tickets (must be at least 0):

Number of tickets ---------->

Price per ticket ------------->

Total amount due ---------->

Would you like to make another raffle ticket purchase? (y/n)

/* If y, loop back to beginning. If n, proceed to next. */

Total cost of all tickets ---->

/*==============================================*/

Can someone please help me with this? I know it's not that difficult but I'm totally lost and so exhausted! Here is the code I've written so far:
