I'm having trouble with two problems. Please show your work so I can understand how to solve. Thanks!

A broker friend of yours wants you to deposit your money with his firm's money market account. You have $12,000 today. Your friend says that if you deposit the $12,000 and a yearly deposit of $15,000, his firm can convert it into $2.5 million dollars within 25 years. What rate will your money market have to earn to be able to achieve this? 0 8.75% ? 10.24% ? 11.56% ? 12.78%
