Question
Use the formula $A=p\left(1+\frac{r}{n}\right)^{n}$ to answer Exercises 101-104.Frank initially invested $\$ 500$ in a savings account where interest is compounded annually. If after 2 years the amount in the account is $\$ 540.80$, determine the annual interest rate.
Step 1
Initial investment (principal), p = $500 Number of years, t = 2 Final amount, A = $540.80 Number of times interest is compounded per year, n = 1 (since it's compounded annually) Show more…

For the following exercises, use the compound interest formula, $A(t)=P\left(1+\frac{r}{n}\right)^{n t}$. Use the formula found in the previous exercise to calculate the interest rate for an account that was compounded semi-annually, had an initial deposit of $\$ 9,000$ and was worth $\$ 13,373.53$ after 10 years.

Use the following information and formula. Money in a savings account that earns interest at r percent compounded annually will grow according to the formula $$A=P(1+r)^{t}$$ where $A=$ Account balance in dollars $t=$ Time in years $P=$ Principal in dollars (amount deposited) $r=$ Interest rate compounded annually Find the interest rate that will turn a deposit of $\$ 15,000$ into $\$ 15,606$ in 2 years.
