Tina is saving up to treat herself and her best friend to a trip to. She figures travel will be back to normal in three years, and that gives her three years to save up. She expects the entire trip to cost $3550. She is able to deposit $450 now from her tax refund into her savings account which has a 1.3% APR. She wants to know what monthly payment she will need to add to the account to save up the rest of the cost in time for the trip.
