12. An insurance agent offers services to clients who are concerned about their personal financial planning for retirement. When explaining the advantages of an early start to investing, she uses the example of 25year old Jabu who started to save R2 000 a year for 10 years (and made no further contributions after age 34). Jabu earned more than Jane who waited 10 years, and then saved R2 000 a year from the age of 35 until her retirement at age 65 (a total of 30 yearly payments!). Find the net earnings (compoundamount minus contributions) of Jabu and Jane at age 65. An annual interest rate of 7,5% was applicable and the deposits were made at the beginning of each year.
