programming c#

Hello

I have a programming class ( we work in visual studio) c# language

I want someone to help me in assignment ( I have a design interface and I need the code)

I attached the interface and notepad for the coding

using System;
. . .
namespace paymentCalcApp2017c1_proj
{
public sealed partial class MainPage : Page
{
. . . intTerms . . . ;
. . . intPercents . . . };

{
this.InitializeComponent();

{
intTerm = intTerms[intTermIndex];
