the principal is p = 800 $
rate of interest is r = 20 %
time is t = 4 years.
the expression for the Amount after four years is given as follows,
[tex]A=p(1+\frac{r}{100})^t[/tex]put the values,
[tex]A=800\times(1+\frac{20}{100})^4[/tex][tex]\begin{gathered} A=800\times(\frac{120}{100})^4 \\ A=800\times2.0736 \\ A=1658.88\text{ \$ } \end{gathered}[/tex]so the worth of the stock is 1658.88 $ now.
thus, the answer is 1658.88 $
