(financial mathematics) A small business borrows $12,000 at nominal interest 12% compounded quarterly, to help cover start-up costs. Payout $750 done at the end of every 6 months during the time required to pay return the loan. Three months before the 9th payment is due, the company refinancing a loan with a nominal interest rate of 9%, compounded monthly. Under this refinancing scheme, a payment of R must be made every month, with the first monthly payment starting when it should be 9th payment based on old loan. In total there are 30 monthly payments which will fully repay the loan. Determine the R value.
