Financial contracts involving investments, mortgages, loans, and so on are based on either a fixed or a variable interest rate. Assume fixed interest rates. Sheila plans to loan her friend $700. Her friend will pay a simple interest rate of 7.8% every year. If no payments are made and no further borrowing occurs between them for five years, how much money will Sheila's friend owe her then? $758.86 $1,019.04 $973.00 $273.00 If interest is accrued at 7.8% compounded annually, all other things being equal, how much money will Sheila's friend owe her in five years? $754.60 $1,019.04 $973.00 $397.43 Sheila has another investment option in the market that pays 7.8% nominal interest, but it's compounded quarterly.
