Answer:
This question is incomplete since the interest rate is not included and so is the requirement. However, if it asking for the annual contributions Bonnie can make, you can calculate it as shown below and assuming a discount rate of 10%;
Explanation:
Since Bonnie's goal is $300,000, this will be the future value and you can use a financial calculator to solve for recurring deposits (PMT);
Time to retirement; N = 12
Interest rate; I/Y = 10%
Future value; FV = 300,000
One time present cashflow; PV = 0
then compute the recurring deposits; CPT PMT = 14,028.995
Therefore, she will need to contribute $14,029 every year to meet her goal.
