1. Suppose you have $12,000 in a savings account. You would like to make weekly withdrawals of $63 from this account for the next 4 years. What annual interest rate would you need? Answer in percent, rounded to one decimal place (e.g., 6.71% --> 6.7)

2. Suppose the Dutch Water Authority wanted to raise money by selling perpetuities of $140 per year, with the first cash flow paid in one year from today. If the appropriate discount rate is 5.5%, what would you be willing to pay today for this perpetuity? Round to the nearest dollar.

3. Suppose you make the following deposits into an account earning 2.0%: $13,000 today followed by $5,000 each year for the next 7 years (so the last cash flow is at year 7). How much will you have in the account after 11 years? Round to the nearest dollar.
