PLEASEEEE HELP!!!!!!
 Suppose that you invest $400 in a bank account that has APR of 6% and it is compounded monthly (12 times a year)
 If we use the formula F = P*(1 + r)t , What is the value for "r"?
 so, if you invest $400 in this account, how much money will you have after 1 month?
 AND How much money will you have in your account after 1 year?
