5. Finding the interest rate and the number of years The future value and present value equations also help in finding the interest rate and the number of years that correspond to present and future value calculations. If a security currently worth $9,200 will be worth $15,767.18 seven years in the future, what is the implied interest rate the investor will earn on the security—assuming that no additional deposits or withdrawals are made? 8.00% 6.40% 5.83% 0.24% If an investment of $50,000 is earning an interest rate of 8.00%, compounded annually, then it will take for this investment to reach a value of $89,052.92—assuming that no additional deposits or withdrawals are made during this time. Which of the following statements is true—assuming that no additional deposits or withdrawals are made? If you invest $5 today at 15% annual compound interest for 82.3753 years, you’ll end up with $100,000. If you invest $1 today at 15% annual compound interest for 82.3753 years, you’ll end up with $100,000.

answer to first question:

(1 + i)⁷ = $15,767.18 / $9,200 = 1.713824

⁷√(1 + i)⁷ = ⁷√1.713824

1 + i = 1.08

i = 8%

answer to second question:

(1 + 8%)ⁿ = $89,052.92 / $50,000 = 1.7810584

1.08ⁿ = 1.7810584

n = log 1.7810584 / log 1.08 = 0.25067816 / 0.033423755 = 7.5 years

answer to third question:

If you invest $1 today at 15% annual compound interest for 82.3753 years, you’ll end up with $100,000.

FV = $1 x 1.15⁸²°³⁷⁵³ = $100,000

steering wheels are always situated on the left side of the car.

always drive on the right side of the road.

white lines separate lanes of traffic traveling the same direction.

hashed or broken lines means you may change lanes when it is safe.

solid white lines mean stay in your lane.

yellow lines separate traffic moving in opposing directions.

hashed or broken yellow lines mean you can carefully pass, paying attention to oncoming traffic.

never cross a solid yellow line (or double yellow line).

when turning left at an intersection, pass in front of any cars that are turning left from the opposing direction (do not try to pass behind them).

use the left lane to pass other cars traveling your direction.

do not pass in the right lane unless absolutely necessary.

if you are driving in the far left hand lane and someone would like to pass you, move over to the right lane when it is safe to do so and allow them to pass.

you must always yield to pedestrians.

come to a complete stop whenever you see pedestrians trying to cross the street.

never pass a school bus if it has flashing red lights. wait until the lights have stopped.

be aware of bicyclists. often they share the road with cars and are supposed to also follow general traffic laws.

be particularly careful about driving in cities with bike lanes -- always check before turning that a bike is not coming.

it is mandatory to pull over or stop at an intersection to allow an emergency vehicle to pass you if you see one traveling with lights flashing and/or a siren running.

do not overuse your car horn. horns are used almost exclusively for emergency situations or for when you feel unsafe.
