Problem 7. Please show work with using the formulas.

How long will it take $3,000 to accumulate to $10, 235, if the interest rate is 1% 2% 5% 10% 20% 50% (Solving for interest rate) At what interest rate will $3,000 accumulate to $10, 235, if the time to maturity is 2 years 5 years 10 years 15 years (Solving for interest rate) At what interest rate will $1,000 accumulate to $100,000, if the time to maturity is 10 years 20 years 30years 50 years (Solving for PV) If you were guaranteed $50,000 in 5 years or $75,000 in 8 years, which would you accept your opportunity cost is 1 5%? What if your opportunity cost is 5%? (Solving for PV) If you were guaranteed $60,000 in 6 years or $95,000 in 8 years, which would you accept your opportunity cost is 15%? What if your opportunity cost is 5%? (Solving for PV of Ordinary annuity) You are expected to receive $20,000 at the end of each of the next 30 years. If the opportunity cost of capital (interest rate) is 12% per year, compounded annually, what is its present value
