$\"5000%2B6%285000x%29=6200\"$ (to get this equation, i looked at what i would do to say get 10% of 5000 and thats multiply ing .10 by 5000 to get the amount of interest for 1 year, since there are 6 years u have to multiply the % for a year by 6)
\n" ); document.write( " $\"5000%2B6%285000x%29=6200\"$ solve for x
\n" ); document.write( " $\"5000%2B%2830000x%29=6200\"$
\n" ); document.write( " $\"%2830000x%29=1200\"$
\n" ); document.write( " $\"x=.04\"$
\n" ); document.write( "4% interest \r
