You deposit $800 in an account that pays 2.65% annual interest compounded continuously. What is the balance after 12 years? Use
balu736 [363]

Answer:Let P = initial investment

     r = annual interest rate (decimal form)

     t = number of years

   A(t) = amount after t years

 

Then, A(t) = Pert

 

A(12.5) = 800e(0.0265)(12.5)

 

             = 800e0.33125

 

             = $1114.17

4/10x - 2x + 8/5 = 4/5
mamaluj [8]

\large\displaystyle\text{$\begin{gathered}\sf \left(\frac{4}{10}\times x\right)-(2 \times x)+\frac{8}{5}=\frac{4}{5}    \end{gathered}$}

Reduce the fraction 4/10, to its minimum expression, extracting and canceling 2.

  • \large\displaystyle\text{$\begin{gathered}\sf \frac{2}{5}x-2x+\frac{8}{5}=\frac{4}{5}    \end{gathered}$}

Combine \bf{\frac{2}{5}x } and -2x to get \bf{-\frac{8}{5}x}.

  • \large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x+\frac{8}{5}=\frac{4}{5} \     \end{gathered}$}

Subtract 8/5 from both sides.

  • \large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x=\frac{4}{5}-\frac{8}{5} \ \    \end{gathered}$}

Since 4/5 and 5/8 have the same denominator, join their numerators to subtract them.

  • \large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x=\frac{4-8}{5}   \end{gathered}$}

Subtract 8 from 4 to get -4.

  • \large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x=-\frac{4}{5}   \end{gathered}$}

Multiply both sides by \bf{-\frac{5}{8}}, the reciprocal of \bf{-\frac{5}{8}}.

  • \large\displaystyle\text{$\begin{gathered}\sf x=-\frac{4}{5}\left(-\frac{5}{8}\right)   \end{gathered}$}

Multiply -4/5 by -5/8 (to do this, multiply the numerator by the numerator and the denominator by the denominator).

  • \large\displaystyle\text{$\begin{gathered}\sf x=\frac{-4(-5)}{5\times8} \ \to \ \ Multiply  \end{gathered}$}
  • \large\displaystyle\text{$\begin{gathered}\sf x=\frac{20}{40}  \end{gathered}$}

Reduce the fraction 20/40 to its lowest expression by extracting and canceling 20.

  • \boxed{\large\displaystyle\text{$\begin{gathered}\sf x=\frac{1}{2}  \end{gathered}$}}
