At the end of one year, Sheridan Service borrowed an additional $4000. Six months later, the line of credit loan was converted into a collateral mortage loan. What was the amount of the mortgage loan if the line of credit interest was 9% compounded monthly? A $2800 promissory note issued without interest for five years on September 30, 2015, is discounted on July 31, 2018, at 8% compounded quarterly. Find the compound discount. On April 15, 2019, a 10-year note dated June 15, 2014, is discounted at 10% con pounded quarterly. If the face value of the note is $4000 and interest is 8% compounded quarterly, find the compound discount.
