QuestionC# noob: Making Textbox entry a percentage, and Help with loops Pin

Hi, New here, and would be very thankful for any help someone can give me.

The code I am working for is a population estimator. It has 3 text boxes, the first is two enter the starting population, the second is to enter the daily increase in that population in a percentage, and the third is the number of days to multiply that by.

My first issue is with the second text box. I don't know how to enter the data as a percent. As of now it is only entering as a whole number, so I when I right in text box one the number 2, in box2 the number 30, and in three the number 10, I get the 302. Not 21.209 like it should be.

Secondly, it all displays in a listbox, and its supposed to loop for every day you enter. I've got the loop to loop by days, but it just runs the same calculation, I want it make every entry build off the last.
Example:
It should say
2
2.6
3.38
4.394
5.7122
etc

I've entered in the code below.
Thanks for any help!

private void calculateButton_Click(object sender, EventArgs e)
       {
           int organisms;
           int days;
           int growth;
           int population;
           int count = 1;
 
           if (int.TryParse(OrganismsTextbox.Text, out organisms))
           {
               if (int.TryParse(DailyTextbox.Text, out growth ))
 
               {
 
                   if (int.TryParse(DaysTextbox.Text, out days))
 
                       do
                       {
 
                           population = organisms + growth * days;
                           resultsListbox.Items.Add("The population For day " + count + " is " + population.ToString("n1"));
 

                           count = count + 1;
                       }
                       while (count <= days);
