tina is saving up money to buy a car. tina puts $10,000.00 into an account which earns 4% interest, compounded monthly. how much will she have in the account after 3 years? use the formula $a = p(1+\frac{r}{n})^{nt}$, where $a$ is the balance (final amount), $p$ is the principal (starting amount), $r$ is the interest rate expressed as a decimal, $n$ is the number of times per year that the interest is compounded, and $t$ is the time in years. round your answer to the nearest cent.
Answer
Explanation:
Step1: Identify the values
$P = 10000$, $r=0.04$, $n = 12$, $t = 3$
Step2: Substitute values into formula
$A=10000\left(1+\frac{0.04}{12}\right)^{12\times3}$
Step3: Calculate the exponent part
$12\times3 = 36$, $\frac{0.04}{12}\approx0.00333$ $1+\frac{0.04}{12}=1 + 0.00333=1.00333$
Step4: Calculate the power part
$(1.00333)^{36}\approx1.12727$
Step5: Calculate the final amount
$A = 10000\times1.12727 = 11272.71$
Answer:
$11272.71$
