How would I solve this?
\n" ); document.write( "An investment of $1500 paid interest of $45 during a certain period. How much interest would an investment of $2000 invested at the same rate for the same length of time pay?
\n" ); document.write( "--------------
\n" ); document.write( "I = Prt
\n" ); document.write( "---
\n" ); document.write( "45 = 1500rt
\n" ); document.write( "I = 2000rt
\n" ); document.write( "-------
\n" ); document.write( "Set up a proportion:
\n" ); document.write( "I/45 = 2000/1500
\n" ); document.write( "I = 45(2000/1500)
\n" ); document.write( "I = 45(4/3)
\n" ); document.write( "---------------------
\n" ); document.write( "Interest on $2000 = $60
