Savings Investigation  Sammy and Oscar have been allocated £4000 with a 2 year period of time. Their task is to investigate the current savings options available for the amount they have been given.  To do this, they will find 5 different savings accounts from a range of banks. they must assume that the money and the interest earned stays in the account until my investment period is up. Compound interest formula:A=P (1+R/100) ^nA-amount earnedP-principal amountR- Raten- How long (per annum) In order to understand the process of compound interest, they will find the total interest earned from the first bank without using the formula.
