Charlie earns $4,900 in simple interest on a sum of
\n" ); document.write( "money invested for 5 years at a 7% interest rate.
\n" ); document.write( "------
\n" ); document.write( "Find the sum invested:
\n" ); document.write( "I = P*r*t
\n" ); document.write( "4900 = P*0.07*5
\n" ); document.write( "P = $14000
\n" ); document.write( "==================\r

\n" ); document.write( "the same sum of money for 6 years at a 6% interest rate?
\n" ); document.write( "-------
\n" ); document.write( "Find \"I\":
\n" ); document.write( "I = P*r*t
\n" ); document.write( "I = 14000*6*0.06
\n" ); document.write( "Interest = $5040
