sidney has $8,684 in an account that earns 10% interest compounded annually. to the nearest cent, how much will she have in 4 years? use the formula $b = p(1 + r)^t$, where $b$ is the balance (final amount), $p$ is the principal (starting amount), $r$ is the interest rate expressed as a decimal, and $t$ is the time in years.
Answer
Explanation:
Step1: Identify values
$p = 8684$, $r=0.1$, $t = 4$
Step2: Substitute into formula
$B = 8684\times(1 + 0.1)^{4}$
Step3: Calculate exponent
$(1 + 0.1)^{4}=1.1^{4}=1.4641$
Step4: Calculate final amount
$B = 8684\times1.4641=\ 12714.2444$
Answer:
$12714.24$
