henry has $3,261 in an account. the interest rate is 5% compounded annually. to the nearest cent, how much interest will he earn in 1 year? 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
Answer:
$163.05
Explanation:
Step1: Convert interest rate to decimal
$r = 5%=0.05$
Step2: Identify principal and time
$p = 3261$, $t = 1$
Step3: Calculate balance
$B=p(1 + r)^t=3261\times(1 + 0.05)^1=3261\times1.05 = 3424.05$
Step4: Calculate interest
$I=B - p=3424.05-3261=163.05$
