Suppose that on January 1, 2019, you invest $1,000 in an account that pays 5% interest. As before, you have plans to withdraw $300 after one year and to deposit an additional $1,000 after two years.  lets assume that interest is paid AND compounded TWICE each year (i.e. semi-annually). 

 Questions

Does this change the rate which money accumulates in your account?  What is the amount? 

Does your number show that semi-annual compounding resulting in a higher balance?
