Tonya has $150.00 on her credit card.  If she leaves any balance on her card at the end of the month, she is charged 20% interest.  If she makes a $50.00 payment on her card, what will be the new balance?
Her card has a $150.00 balance and she makes a $50.00 payment so the new balance is 150-50 = $<<150-50=100.00>>100.00
She didn't pay it off so she is charged 20% interest on her $100.00 balance so the interest is .20*100 = $20.00
Her balance was $100.00 and she was charged $20.00 in interest so her new balance is 100+20 = $<<100+20=120.00>>120.00

Tonya'nın kredi kartında 150.00 $ var.  Ay sonunda kartında herhangi bir bakiye bırakırsa, %20 faiz uygulanır.  Eğer kartında 50,00$'lık bir ödeme yaparsa, yeni bakiyesi ne olur?
Kartında 150,00 $ bakiye var ve 50,00 $ ödeme yapıyor, böylece yeni bakiye 150-50 = $<150-50=100,00>>100,00
Kartını kapatmadığı için 100,00$'lık bakiyesine %20 faiz uygulandı, yani faiz .20*100 = 20,00$
Bakiyesi 100,00 $ idi ve 20,00 $ faiz ödedi, böylece yeni bakiyesi 100+20 = $<100+20=120,00>>120,00
