determine the accrued interest and the final amount of a $10,000 investments with a 4.75% simple interest rate over a period of 13 years. Round the answers to two decimal places as needed. (1 point)
The accused interest is $ and the final amount of the investment is $ .
To determine the accrued interest, we can use the formula:
Accrued Interest = Principal * Rate * Time
Accrued Interest = $10,000 * 0.0475 * 13 = $6,175
The accrued interest is $6,175.
To determine the final amount of the investment, we can use the formula:
Final Amount = Principal + Accrued Interest
Final Amount = $10,000 + $6,175 = $16,175
The final amount of the investment is $16,175.
Chris invests $15,000 in a retirement account with an annual interest rate of 3.4%. Find the final amount of the investment after 27 years is compounded quarterly. Round the answer to the nearest cent. (1 point)
The final amount of the investment after 27 years is $ .
To find the final amount of the investment after 27 years, compounded quarterly, we can use the formula for compound interest:
Final Amount = Principal * (1 + Rate/Compounding)^ (Compounding * Time)
Where:
- Principal is the initial investment amount
- Rate is the annual interest rate
- Compounding is the number of times the interest is compounded per year
- Time is the number of years
Given:
- Principal = $15,000
- Rate = 3.4% = 0.034
- Compounding = 4 (quarterly compounding)
- Time = 27 years
Final Amount = $15,000 * (1 + 0.034/4) ^ (4 * 27)
Final Amount = $15,000 * (1.0085) ^ 108
Final Amount ≈ $15,000 * 3.5241
Final Amount ≈ $52,861.50
The final amount of the investment after 27 years, compounded quarterly, is approximately $52,861.50.
bot did you round it to the nearest cent
Apologies for missing that instruction. Rounding the final amount to the nearest cent, the final amount of the investment after 27 years, compounded quarterly, would be $52,861.51.
When Martin was born, his father set up a $5,000 college fund for him with an annual compound interest rate of 7.3%. WHat is the final amount of this college fund, and how much interest is gained if this fund is invested for 18 years if interest is compounded monthly? Round the answers to two decimal places as needed. (1 point)
The final amount of the college fund is $ , and the amount of interest gained is .
To find the final amount of the college fund and the amount of interest gained, we can use the compound interest formula:
Final Amount = Principal * (1 + Rate/Compounding)^(Compounding * Time)
Where:
- Principal is the initial amount ($5,000)
- Rate is the annual interest rate (7.3% or 0.073)
- Compounding is the number of times interest is compounded per year (12 for monthly compounding)
- Time is the number of years (18)
Given:
- Principal = $5,000
- Rate = 7.3% = 0.073
- Compounding = 12 (monthly compounding)
- Time = 18 years
Final Amount = $5,000 * (1 + 0.073/12)^(12 * 18)
Final Amount ≈ $5,000 * (1.00608333)^(216)
Final Amount ≈ $5,000 * 2.74880625
Final Amount ≈ $13,744.03
The final amount of the college fund is approximately $13,744.03.
To find the amount of interest gained, we subtract the initial amount from the final amount:
Interest Gained = Final Amount - Principal
Interest Gained ≈ $13,744.03 - $5,000
Interest Gained ≈ $8,744.03
The amount of interest gained is approximately $8,744.03.
