Question 606441
Start with the simple interest formula
{{{I = prt}}}
{{{p =200}}}
{{{t=5}}}
{{{I=60}}}
Substitute the values into the formula.
{{{I = prt}}}
{{{60 = 200(r)5)}}}
Multiply on the right side.
{{{60 = 1000r}}}
divide both sides by 1000
{{{(60)/(1000) = (1000r)/(1000)}}}
reduce
{{{6/100 = r}}}
Change the fraction to a percent
6% = r
