spencer deposited $10 in an account earning 5% interest compounded annually. to the nearest cent, how much will he have in 3 years?
Answer
Explanation:
Step1: Identify the compound - interest formula
The compound - interest formula is $A = P(1 + r)^t$, where $A$ is the amount of money accumulated after $n$ years, including interest, $P$ is the principal amount (the initial amount of money), $r$ is the annual interest rate (in decimal form), and $t$ is the number of years the money is invested for.
Step2: Convert the interest rate to decimal
The annual interest rate $r = 5%=0.05$, the principal amount $P = 10$, and the number of years $t = 3$.
Step3: Substitute the values into the formula
$A=10\times(1 + 0.05)^3$. First, calculate $(1 + 0.05)^3=(1.05)^3=1.05\times1.05\times1.05 = 1.157625$. Then, $A = 10\times1.157625=11.57625$.
Step4: Round to the nearest cent
Rounding $11.57625$ to the nearest cent gives $11.58$.
Answer:
$11.58$
