Jermaine lives in a world where the nominal interest rate is 3% and the inflation rate is 1%. today, jermaine has $200, with which he could purchase 80 zaps. however, jermaine realizes he could also put the money in savings for one year; if he did this, then in one year's time he would have –more and would be able to purchase – more zaps. (assume that the price change for zaps reflects the general inflation rate.)

Divide $200 by 80 to get $2.50 price per zap. At 3%, Jermaine's $200 would grow to $206 ($200 x 1.03) = $206 by the end of the year. At the end of one year he would have $6 more and would be able to purchase two more zaps (2 X ($2.50 X 1.03), or 2 X $2.575 = $5.15) He would have $.85 left in change.

Secured loans are protected by collateral security. examples: title loans where the borrower uses the car title as collateral security interest rates are lower and repayments are longer therefore risk is low as a collateral security is given as guarantee to the bank in case of failure to pay the loanunsecured loans are not protected by collateral security but it is given on the creditworthiness of the borrower, trusting that she/he will pay on time. examples; payday loans is a short term loan where the borrower lends money from the bank and pays is back when the borrower receives his/her wages.interest rates are high and repayments are shorter. but the risk is high as no collateral security is given as a guarantee to the bank for payment of the loan
