If you make monthly payments of $596.59 per month, how long i.e., number of months rounded to one decimal place) will it take you to fully repay the loan? 26. It is now January 1. You plan to make 5 deposits of $300 each, one every 6 months, with the first payment being made exactly six months from today.
