Answer:
3 months
Step-by-step explanation:
Without the 5% interest it would take 2 months to pay it off but with the 5% interest added that's going to 5% of whatever the balance is.
After her 1rst payment of 60$ she will have 66$ left to pay: 120(1/20)+6-60
After her 2nd payment of 60$ she will have 9.3$ left to pay: 66(1/20)+ 3.3-60
so basically 2 payments of $60 and one payment of $0.47
