Question 1

If you deposit $900 into an account for two years and the interest rate is 4%, how much do you have at the end of the two years?

Accepted Answer

First, we need to calculate the interest earned after two years: 
Interest = Principal x Rate x Time = $900 x 0.04 x 2 = $72. 
Then, we add the interest earned to the initial deposit: 
Final amount = $900 + $72 = $972. 
The closest option is B, which is $973.44. However, this seems to be a rounding error, as the exact answer should be $972.

Question 2

You are tearing down a building and find $1 in change that someone lost when working on the building 140 years ago. If, instead of being careless with the $1 in change, this person had deposited it into a bank and earned 2 percent interest every year for 140 years, how much would be in the account today according to the rule of 70?

Accepted Answer

According to the rule of 70, we divide 70 by the interest rate (2%) to find the approximate number of years it takes for the money to double. In this case, it would take approximately 35 years for the money to double. Therefore, after 140 years, the money would have doubled 4 times (since 140 divided by 35 equals 4). So the original $1 would have turned into $16 (1 doubled 4 times). Therefore, the best choice is C, $16.

Question 3

If you put $1,000 in the bank today at an interest rate of 6% what is its value in two years?

Accepted Answer

The formula for calculating compound interest is A=P(1+r)^n, where A is the final amount, P is the principal (initial amount), r is the interest rate expressed as a decimal, and n is the number of compounding periods. Plugging in the given values, we get A = $1,000(1+0.06)^2 = $1,123.60. Therefore, choice C is the correct answer. Choice A is incorrect because it does not take into account the compounding of interest. Choice B is incorrect because the formula does not make sense mathematically. Choice D is incorrect because one of the other choices is correct.

Question 7

According to the rule of 70, if a person's saving doubles in 10 years, what interest rate were they earning?

Accepted Answer

The rule of 70 states that to find the approximate number of years for an investment to double, divide 70 by the interest rate. Therefore, if the savings doubled in 10 years, we can divide 70 by 10 to find the interest rate, which is 7.

Question 8

What is the present value of a payment of $2,000 to be received two years from today if the interest rate is 5%?

Question 9

You receive $500 today which you plan to save for two years. Also, in two years you will be given another $500. If the interest rate is 5 percent, what is the present value of the payment of $500 today and the $500 in two years?

Accepted Answer

To find the present value of the payments, we need to discount them to their present value using the given interest rate of 5 percent.

The first payment of $500 today has a present value of $500.

The second payment of $500 in two years has a present value equal to:

$500/(1.05)^2 = $453.51

Therefore, the total present value of the payments is:

$500 + $453.51 = $953.51

So, the correct answer is C.

Question 10

You could borrow $1,000 today from Bank A and repay the loan, with interest, by paying Bank A $1,060 one year from today. Or, you could borrow $1,500 today from Bank B and repay the loan, with interest, by paying Bank B $1,600 one year from today. Which of the following statements is correct?

Accepted Answer

We can calculate the interest rates on both loans using the formula:

Interest Rate = (Total Repayment - Loan Amount) / Loan Amount x 100%

For Bank A:

Interest Rate = ($1,060 - $1,000) / $1,000 x 100% = 6%

For Bank B:

Interest Rate = ($1,600 - $1,500) / $1,500 x 100% = 6.67%

Therefore, the interest rate on the loan from Bank A is lower (6%) than the interest rate on the loan from Bank B (6.67%). So, the correct statement is that the interest rate on the loan from Bank A is lower than the interest rate on the loan from Bank B.

Question 11

The future value of $500 saved for two years at an interest rate of 5% is

Accepted Answer

The formula for future value with compound interest is:
FV = PV x (1 + r/n)^(n*t)
where PV is the present value (in this case $500), r is the annual interest rate (5%), n is the number of times the interest is compounded per year (assuming once per year, so n = 1), and t is the time period (2 years).

Plugging in the values, we get:
FV = $500 x (1 + 0.05/1)^(1*2) = $500 x 1.1025 = $551.25

Therefore, the best choice is C, which matches this result.

Question 12

Will is risk averse and has $1,000 with which to make a financial investment. He has three options. Option A is a risk-free government bond that pays 5 percent interest each year for two years. Option B is a low-risk stock that analysts expect to be worth about $1,102.50 in two years. Option C is a high-risk stock that is expected to be worth about $1,200 in four years. Will should choose

Accepted Answer

Will is risk averse, which means he prefers a certain outcome with lower returns to an uncertain outcome with higher returns. Option A, the risk-free government bond, offers a certain outcome of earning 5 percent interest each year for two years, resulting in a total return of $1050. Option B, the low-risk stock, has an uncertain outcome but is expected to be worth about $1102.50 in two years, resulting in a total return of about 10.25 percent. Option C, the high-risk stock, has the highest uncertain outcome but is not a good choice for Will as he is risk averse and does not want to take that level of risk. Therefore, option A is the best choice for Will.
