a) Lynn Company has a machine that cost $100,000. It is to be leased to Lorne Company for 15 years, with the rental payments made at the beginning of each year. Lynn wants a return of 10% on the lease. Compute the annual rental that Lynn will need to charge Lorne to achieve a 10% return.

b) Jane Doe is 25 years old and wants to retire at the age of 50. In order to be able to retire, Jane figures that she needs to have a sufficient amount in her savings account at the retirement date to enable her to withdraw $50,000 at the end of each year for the following 30 years. Jane has just inherited $100,000, which she intends to deposit today to start her retirement fund. Additionally, she will make a deposit at the end of each year for the next 25 years until she reaches 50. How much should each annual deposit be? (Assume that Jane's long-term interest rate is 6%.)
