The only problem I have with my code is the result(no errors or warnings). It always gives me $2005371809 as my answer. for example, for each of my prices I input 300, 50, and 10 dollars as my sample data. The answer should have been $360 instead of that huge number as indicated by my formula. Also, please offer some suggestions to improve my program if you can.
Edit- Do you think this junk value that keeping getting has to do with the data types that I'm using?
Edit 2- well I've made huge progress by creating 3 new variables(int price 1, 2 and 3.) and by putting the formula inside the last else if statement(I'm not sure if that did anything really). The problem now is that I am force to input 3 integers otherwise the answer is off by 1 or 2. for example, if you only pick option 2 and input 300 and decide to press option 5, then the answer will be 302. Another example is if you input 300 then 50, you get 351. Most likely it has something with not inputting a value in one of the variables(like inputting 300 in price1, but leaving price2 and 3 empty.). So my new question is how do I force the program to leave price2 or 3 as 0 in case a customer only wants to inputs a value in price1. Do I have to create multiple formulas to do that?

}
Well I was finally able to solve my dilemma(took about 3 hours jeesh). All I had to do was set all of my 3 price variables to 0 so that It wouldn't give my any junk values.
