On January 1, 2003. you plan to take a trip around the world upon graduation four years from now.

Your grandmother wants to deposit sufficient funds for this trip in a savings account for you. On the basis of a budget, you estimate that the trip currently would cost $15,000. To be generous, your grandmother decided to deposit $3,500 in the fund at the end of each of the next four years, starting on December 31, 2003. The savings account will earn 6 percent annual interest, which will be added to the savings account at each year-end.

Required (show computations and round to the nearest dollar): 1. How much money will you have for the trip at the end of year 4 (i.e., after four deposits)? 2. What is the interest for the four years '.' 3. How much interest revenue did the fund earn in 2003. 2004, 2005, and 2006?
