Question 1177182
{{{A = P(1 + rt)}}}

First, converting {{{R}}} percent to {{{r}}} a decimal
{{{r = R/100 = 8/100 = 0.08}}} per year.

Putting time into years for simplicity,
{{{6/12}}} year = {{{0.5}}} years 

Solving our equation:

{{{A = 39000(1 + (0.08 * 0.5)) }}}
{{{A = 40560.00}}}=>the future value 

The total amount accrued, principal plus interest, from simple interest on a principal of ${{{39000.00}}} at a rate of {{{8}}}% per year for {{{0.5}}} years ({{{6}}} months) is ${{{40560.00}}}.

{{{I = A - P =40560.00-39000 =1560.00}}}=> interest earned
