Final answer:
Tyee needs to invest a certain amount of money in an account with a 4.7% interest rate compounded monthly to reach $98,000 in 8 years. To find this initial investment, we use the compound interest formula and solve for the principal (P), then round the result to the nearest dollar.
Step-by-step explanation:
To determine how much Tyee needs to invest to have an account value reach $98,000 in 8 years with an interest rate of 4.7% compounded monthly, we can use the formula for compound interest:
![\[A = P \left(1 + (r)/(n)\right)^(nt)\]](https://img.qammunity.org/2024/formulas/business/high-school/qbt64n0zcusl0cr29qewk9ldkubuogsf2v.png)
Where:
- A is the future value of the investment/loan, including interest.
- P is the principal investment amount (initial deposit or loan amount).
- r is the annual interest rate (decimal).
- n is the number of times that interest is compounded per year.
- t is the time the money is invested or borrowed for, in years.
In this case, we're solving for P and we have:
- A = $98,000
- r = 4.7% = 0.047 (as a decimal)
- n = 12 (since interest is compounded monthly)
- t = 8 years
Substituting these values into the formula gives us:
![\[98,000 = P \left(1 + (0.047)/(12)\right)^(12 \cdot 8)\]](https://img.qammunity.org/2024/formulas/business/high-school/wws4edwpb42tb4ce5fe9jiafqv65qzxtbi.png)
Calculating the right side of the equation:
![\[P = (98,000)/(\left(1 + (0.047)/(12)\right)^(96))\]](https://img.qammunity.org/2024/formulas/business/high-school/q72kv0r2hk5tvhj4boz74xqgm57dun1y56.png)
After solving this on a calculator, you would round the final value to the nearest dollar to find the amount Tyee needs to invest initially.
The complete question is: tyee is going invest in an account paying an interest rate of 4.7% compounded monthly. how much would tyee need to invest, to the nearest dollar, for the value of the account to reach 98,000 in 8 years is:
