Ask Anything Monday - Weekly Thread

I'm currently taking my first programming class and we were given a project that I don't really know how to start. The project is to write a program that will allow a grocery store to keep track of the total number of bottles collected for seven days.  The program should allow the user to enter the total number of bottles returned for seven days (enforce a validation of your choice). The program will calculate the total number of bottles returned for the week and the amount paid out (the total returned times .10 cents).  The output of the program should include the total number of bottles returned and the total paid out. 

Can anybody help me out?
