Question: The daycare keeps a waiting list of families who want to place children in the program.

- This waiting list includes family names and contact information, children needing placement, date placement is needed by and comments about placement.

- For each child needing placement, it also records the Childs age and gender.

- the daycare keeps track of tuition payments.  

- Each family pays $X for a child per month in the program.

We track, per family, the tuition amount due, the tuition amount paid, the due date, the date of actual payment, and the payment methods.

I have the answer already but i do not understand it; I need expert to guide through it step by step. thanks!
