How would I solve for this using savings plan formula?

3. Mitch and Bill are both 75 years old. When Mitch was 25 years old, he began depositing $1000 per year into a savings account. He made deposits for the first 10 years, at which point he was forced to stop making deposits. However, he left his money in the account, where it continued to earn interest for the next 40 years.
