If $3000 is deposited in an account that pays 5% interest, what is the difference in the amount after 4 years between the amount

Triss [41]

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$3000\\
r=rate\to 5\%\to \frac{5}{100}\to &0.05\\
t=years\to &4
\end{cases}
\\\\\\
A=3000(1+0.05\cdot 4)\implies \boxed{A=3600}\\\\
-------------------------------\\\\$

$\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$3000\\
r=rate\to 5\%\to \frac{5}{100}\to &0.05\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{annually, thus once}
\end{array}\to &1\\
t=years\to &4
\end{cases}$

$\bf A=3000\left(1+\frac{0.05}{1}\right)^{1\cdot 4}\implies A=3000(1.05)^4\implies \boxed{A=3646.51875}\\\\
-------------------------------\\\\
\stackrel{\textit{compounded interest}}{3646.51875}~~-~~\stackrel{\textit{simple interest}}{3600}$

Can someone explain this.

Answer:

9/4 yds fabric per 1 ft of ribbon

Step-by-step explanation:

3/4 yd fabric is required for every 2/3 ft of ribbon. Let's put this info into an equation of ratios to figure out the number of yards of fabric required for every ONE ft of ribbon:

3/4 yd fabric 2/3 ft ribbon

----------------------- = ---------------------

x 1 ft ribbon

Use cross mult. to solve this. We obtain 3/4 = (2/3)x.

Mult. both sides by (3/2) yields (3/2)(3/4) = (3/2)(2/3)x = x.

This comes out to 9/4 yds fabric per 1 ft of ribbon.
