Brian invested the money for 6 years, so now let's check how much is that for the remaining 4 years.

$\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &2035.3275\\ r=rate\to 4.9\%\to \frac{4.9}{100}\dotfill &0.049\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{yearly, thus once} \end{array}\dotfill &1\\ t=years\dotfill &4 \end{cases}$

$\bf A=2035.3275\left(1+\frac{0.049}{1}\right)^{1\cdot 4}\implies A=2035.3275(1.049)^4 \\\\\\ A\approx 2464.54\implies \boxed{\stackrel{\textit{rounded up }}{A=2465}}$

Brian has 16 yards of chain measured and cut at the. Hardware store. The chain will cost him 47.52$ how much is that per food? _

mojhsa [17]

3 feet= 1 yard

16*3= 48 feet.

47.52/48= 0.99

It will cost Brian $0.99 per foot.

Find the unit rate.

49.50/50= 0.99

No, it wouldn't. It would be the <em>same price

0.99=0.99 It doesn't matter which one Brian chose. </em>

I hope this helps!
