If the rate of annual interest is r% the period is n years and the amount invested is y Then the compound interest is y*(1+r/100)^n - y
Kate invested 4500.
It was eight years.
Multiply the principal (P) by the annual* interest rate as a decimal (r) and the time in years* (t). *The time period may be expressed in months, etc. For example, $2000 invested at 7% simple interest for 5 years: I = Prt = 2000x0.07x5 = 140x5 = $700.
p = principal ie amount invested; r = annual rate of interest; t = time in years. interest receivable = (p x t x r)/100
1 x (1.03)40 = 3.26
>I=Prt > 300=1000(0.03)t > t=10 Time duration will be 10 years.
It would be worth 428.24 if the interest was added on once each year. If the interest were to be compounded monthly rather than annually the value would be 447.67
Simple interest = 700*5/100*2 = 70Simple interest = 700*5/100*2 = 70Simple interest = 700*5/100*2 = 70Simple interest = 700*5/100*2 = 70
