Sorry for all the questions!
In the first problem, "Credit Card Debt," how would one find the total principle paid? I know that in the program below, it is all the values of r added up, but I can't figure out how to deal with it in each separate time it loops.

Best ResponseYou've already chosen the best response.1Total principle paid, start with a var outside your loop. So after you ask the user to input their x, y and z, name a new var and make it equal to 0. a = 0 in the loop, you do something like a = a + r and then at the end when you are printing your results, you just print var a. I think this should get you your total principle paid over 12 months
