Wanda opened a savings account 20 years ago with a deposit of $3,150.37. The account has an interest rate of 4.1% compounded dai

Aleksandr [31]

$\bf ~~~~~~ \stackrel{daily}{\textit{Continuously Compounding Interest Earned Amount}}\\\\
A=Pe^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$3150.37\\
r=rate\to 4.1\%\to \frac{4.1}{100}\to &0.041\\
t=years\to &20
\end{cases}
\\\\\\
A=3150.37e^{0.041\cdot 20}\implies A=3150.37e^{0.82}\implies A\approx 7152.91457$

how much interest is there? well, A - 3150.37.

Please help and thank you

ycow [4]

Answer:

D) 130 workers

Step-by-step explanation:

We have the equation, y = 2x + 40, and y, 300 (since the y-coordinate represents the # of bottles made), so we can solve for x, the number of workers needed.

Substitute: 300 = 2x + 40

Subtract: 260 = 2x

Divide: x = 130

Since x = 130 when y = 300, 130 workers are required to make 300 bottles in a day.
