Question 1197288

given:

{{{P =8500}}}
{{{I=3612.5}}}
{{{t=5}}}

subsitute the values into the formula, 

{{{I =Prt}}}

{{{3612.5 = 8500 * r * 5}}}

{{{3612.5 = 42500r}}}

To find r, divide both sides of the equation with {{{42500}}}.

{{{3612.5 /42500 = 42500r /42500}}}

{{{0.085 = r}}}

Hence,	the interest rate was{{{ 0.085}}}  or {{{8.5}}}%
