Please help



its a schools project... Please help with the task at hand....

I've been assigned a task to design a program for a local Furniture Company. The company allows customers that cannot pay cash for the furniture to pay a deposit and pay the balance in monthly installments, provided that the total amount of the purchase does not exceed R100.000. The amount of the deposit to be paid depends on the total of the purchase.

*The deposit for purchases less than R25.000 is calculated as 5% of the purchase...
