How would I make it where if the In State or Out

of state radio button is clicked each course check box selected will add to the totalPriceLabel in the Payment Imformation section? $49 for In-State. $99 for out of state. (Visual Studio 2017 C#)

This is my code for the checked boxes so far:

Student ID: First Name: Residence Status: Last Name: Out-Of-State Course Order Information private void frenchCheckBox.CheckedChanged(object sender, EventArgs e) \{ numofCourses =i if (frenchcheckBox. Checked) nunofCoursest+; if (germancheckBox. Checked) i nunofCoursest+; if (italiancheckBox. Checked) f nunofCoursest+; if (russiancheckBox. Checked) if (russianCheckBox.Checked) i nunofCoursest+; if (spanishcheckBox. Checked) f nunofCoursest+; totnumberofcoursestabel. Text = nuiofCourses. Tostring O)
