9 and 5/12 - 3 and 2/3
lana [24]
Recall to always convert the mixed fractions to "improper" fractions first,

\bf \stackrel{mixed}{9\frac{5}{12}}\implies \cfrac{9\cdot 12+5}{12}\implies \stackrel{improper}{\cfrac{113}{12}}
\\\\\\
\stackrel{mixed}{3\frac{2}{3}}\implies \cfrac{3\cdot 3+2}{3}\implies \stackrel{improper}{\cfrac{11}{3}}\\\\
-------------------------------\\\\
\cfrac{113}{12}-\cfrac{11}{3}\impliedby \textit{clearly our LCD is 12}\implies \cfrac{113-(4)11}{12}
\\\\\\
\cfrac{113-44}{12}\implies \cfrac{69}{12}\implies 5\frac{9}{12}

What was the interest rate if your balance on an investment of $857 at the end of six years is $1268.36
Pavel [41]

Answer:

The rate of interest is 9.5092%  

Step-by-step explanation:

Given as :

The investment amount = p = $857

The Amount after 6 years = A = $1268.36

The time period = t = 6 years

Let The rate of interest = r%

<u>Now, From Compound Interest method </u>

Amount = Principle × (1+\dfrac{\textrm rate}{100})^{\textrm time}

Or, A = p × (1+\dfrac{\textrm r}{100})^{\textrm t}

Or, $1268.36 = $857 × (1+\dfrac{\textrm r}{100})^{\textrm 6}

Or, \dfrac{1268.36}{857} =  (1+\dfrac{\textrm r}{100})^{\textrm 6}

Or, 1.48 =  (1+\dfrac{\textrm r}{100})^{\textrm 6}

Taking power \dfrac{1}{6}  both side

So, 1.48^{\frac{1}{6}} = ((1+\dfrac{r}{100})^{6})^{\frac{1}{6}}

Or, 10.5092 = 1 + \dfrac{r}{100}

Or, 10.5092 - 1 = \dfrac{r}{100}

Or, 9.5092 = \dfrac{r}{100}

∴   r % = 9.5092

So , The rate of interest = r = 9.5092 %

Hence, The rate of interest is 9.5092%   Answer
