1. How much money would be in a savings count that started with a deposit of $2,000 in year 1 with each succeeding amount increasing by 10% per year? Use an interest rate of 15% per year and a 7-year period.
2. You are a college student making yearly payment for your loan starting from now. For the first three years, you pay $2,500 a year. Year 4 to 6, your parents help you with the payment so you pay $1,500 per year, and finally year 7 you pay $2,500. Determine the value in year 8 that is equivalent to the cash flow stated above. Use an interest rate of 12%.
3. Calculate the present worth in year 0 of the following series of disbursements. Assume that i= 10% per year.

| 3 | 3,500 |   | 9 | 5,000 | 
| 4 | 5,000 |   | 10 | 5,000 |
