Lemme give you a cheap answer, by simply using the "compound interest formula", which is what that is, 2% compounded yearly

thus $\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\qquad 
\begin{cases}
A=\textit{current amount}\to&\boxed{y}\\
P=\textit{original amount deposited}\to &\$23000\\
r=rate\to 2\%\to \frac{2}{100}\to &0.02\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{per year, meaning once}
\end{array}\to &1\\

t=years\to &\boxed{x}
\end{cases}$

plug in those values, and simplify

Mice21 [21]

Answer:

B. Less than a day

Step-by-step explanation:

From the question, the circuit board manufacturer produces 2000 board per hour.

Let x be the number of hours it will take to produce 16500 boards .

That’s

2000 boards = 1 hour

16500 boards = x hour

Cross multiply

xhour x 2000 = 1 x 16500

x hour = 16500/2000

x hour = 8.25 hours

8.25 hours is less than a day
