The formula for calculating simple interest is:
Simple Interest = (Principal) x (Rate) x (Time)
Where:
- Principal is the initial amount invested
- Rate is the annual interest rate
- Time is the time period in years
Given that the principal is $100,000, the rate is 12%, and the time is 6 months (0.5 years), we can plug these values into the formula:
Simple Interest = $100,000 x 0.12 x 0.5
Simple Interest = $6000
Therefore, the simple interest on a $100,000 investment at 12% per year after six months is $6000.

Find the value after five years of a $3000 savings account that pays 3% interest rate, compounded, yearly round to the answer to two decimal places
To calculate the value of a savings account that compounds interest yearly, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
- A is the final amount or value of the account
- P is the principal amount (initial deposit)
- r is the annual interest rate
- n is the number of times the interest is compounded per year
- t is the number of years
In this case, the principal (P) is $3000, the annual interest rate (r) is 3%, the interest is compounded yearly (n=1), and the time period (t) is 5 years.
Plugging these values into the formula:
A = $3000(1 + 0.03/1)^(1*5)
A = $3000(1 + 0.03)^5
A ≈ $3000(1.03)^5
A ≈ $3000(1.1592741)
A ≈ $3477.82
Therefore, the value of the savings account after 5 years, with an initial deposit of $3000 and a 3% interest rate compounded yearly, is approximately $3477.82.

Therefore, the value of the savings account after 5 years, with an initial deposit of $3000 and a 3% interest rate compounded yearly, is approximately $3477.82.
Find the balance after 10 years of a $30,000 savings account that pays 10% interest, compounded, yearly
To calculate the balance of a savings account that compounds interest yearly, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
- A is the final balance of the account
- P is the principal amount (initial deposit)
- r is the annual interest rate
- n is the number of times the interest is compounded per year
- t is the number of years
In this case, the principal (P) is $30,000, the annual interest rate (r) is 10%, the interest is compounded yearly (n=1), and the time period (t) is 10 years.
Plugging these values into the formula:
A = $30,000(1 + 0.10/1)^(1*10)
A = $30,000(1 + 0.10)^10
A ≈ $30,000(1.10)^10
A ≈ $30,000 * 2.59374
A ≈ $77,812.20
Therefore, the balance of the savings account after 10 years, with an initial deposit of $30,000 and a 10% interest rate compounded yearly, is approximately $77,812.20.

Ari is investing 6700 of her savings from her summer job for her college fund. She’s planning to invest the same amount for three years and can choose between simple interest at 6.5% and compound interest at 6% find the difference between these two interest earning types to help Arion decide what investing option
To compare the difference between simple interest at 6.5% and compound interest at 6%, we can calculate the earnings for each investment option.
For simple interest:
Simple Interest = Principal x Rate x Time
Simple Interest = $6,700 x 0.065 x 3
Simple Interest = $1,305
For compound interest, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A is the final amount or value of the investment.
P is the principal amount of the investment.
r is the annual interest rate.
n is the number of times the interest is compounded per year.
t is the number of years.
Using the values given:
P = $6,700
r = 0.06
n = 1 (compounded yearly)
t = 3 years
A = $6,700(1 + 0.06/1)^(1*3)
A = $6,700(1.06)^3
A ≈ $6,700(1.191016)
A ≈ $7,978.11
The difference between the two interest earning types can be calculated by finding the compound interest minus the simple interest:
Difference = Compound Interest - Simple Interest
Difference = $7,978.11 - $1,305
Difference ≈ $6,673.11
Therefore, the difference between compound interest at 6% and simple interest at 6.5% for investing $6,700 for three years is approximately $6,673.11.
For simple interest:
Simple Interest = Principal x Rate x Time
Simple Interest = $6,700 x 0.065 x 3
Simple Interest = $1,305
For compound interest, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A is the final amount or value of the investment.
P is the principal amount of the investment.
r is the annual interest rate.
n is the number of times the interest is compounded per year.
t is the number of years.
Using the values given:
P = $6,700
r = 0.06
n = 1 (compounded yearly)
t = 3 years
A = $6,700(1 + 0.06/1)^(1*3)
A = $6,700(1.06)^3
A ≈ $6,700(1.191016)
A ≈ $7,978.11
The difference between the two interest earning types can be calculated by finding the compound interest minus the simple interest:
Difference = Compound Interest - Simple Interest
Difference = $7,978.11 - $1,305
Difference ≈ $6,673.11
Therefore, the difference between compound interest at 6% and simple interest at 6.5% for investing $6,700 for three years is approximately $6,673.11.
So does she invest compound interest or simple interest?
Based on the calculations, if Ari wants to earn the highest return on her investment, she should choose the compound interest option. Compound interest will earn her approximately $6,673.11 more compared to simple interest over a three-year period. Therefore, investing with compound interest at 6% would be the better choice for Ari.
Find Gina loan, Jerry, 300 and interest rate of 10% a year. How much interest would you get if Jerry pays Gina after sex much
To find the amount of interest that Gina will earn if Jerry pays her after six months, we need to calculate the simple interest using the following formula:
Interest = Principal x Rate x Time
Given that the principal loan amount is $300 and the annual interest rate is 10%, we need to convert the time period to years. As there are 12 months in a year, six months is equal to 0.5 years.
Interest = $300 x 0.1 x 0.5
Interest = $15
Therefore, if Jerry pays Gina after six months, Gina would earn $15 in interest.
Interest = Principal x Rate x Time
Given that the principal loan amount is $300 and the annual interest rate is 10%, we need to convert the time period to years. As there are 12 months in a year, six months is equal to 0.5 years.
Interest = $300 x 0.1 x 0.5
Interest = $15
Therefore, if Jerry pays Gina after six months, Gina would earn $15 in interest.
