When I was just out of college in 1985, I needed a little bit of financial help from my parents to purchase auto insurance and to fix the brakes on my car. I borrowed $400 on July 1, 1985; $500 on January 1, 1986; and $200 on January 1, 1987. In the Summer of 1987 I got a full-time job working at The Hartford Insurance Company as an actuary, and I was able to give my parents two payments of $X on January 1, 1988 and on July 1, 1988 to pay back the loan. We agreed to an interest rate of 3% compounded annually. Find X
