Interest$-$only loan $($regular interest payments each year and principal at maturity$).$ Chuck Ponzi has talked an elderly woman into loaning him $$35,000$ for a new business venture. She has, however, successfully passed a finance class and requires Chuck to sign a binding contract on repayment of the $$35,000$ with an annual interest rate of $10\%$ over the next $20$ years. Determine the cash flow to the woman under an interest$-$only loan, in which Ponzi will pay the annual interest expense each year and pay the principal back at the end of the contract.
