Hi, Just looking for help with these questions, i will post the questions formulas as well. If you could show me how you did it as well that would be appreciated.

1. What effective rate of interest is equivalent to 12% compounded monthly? Express your final answer as a percent.

2.What is the periodic rate of interest if $2000 grows to $4000 in 5 years and 6 months, assuming quarterly compounding?

3.How long will it take an investment of $1500 to grow to $9000 if money can earn 4% compounded semi-annually?

= / (J is over M)

= (1 + ) 1

= (1 + 1) n
