[7 points] Sarah has a saving goal of $30,000 8 years from now. To help her reach the goal, her father offers to give her $3,000 now. Sarah plans to work at a local coffee shop and make 8 additional deposits, one at the end of each year. The first deposit is made at the end of the first year. If all her savings are deposited in a bank that pays 8% interest, how much should her annual deposit be?
