$\"+x+\"$ = number of $1 coins
\n" ); document.write( " $\"+1%2Ax+=+x+\"$ = total value of $1 coins
\n" ); document.write( " $\"+130+-+x+\"$ = number of $.50 coins
\n" ); document.write( " $\"+.5%2A%28+130+-+x+%29+\"$ = total value of $.50 coins
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "Let $\"+T+\"$ = total value of the coins
\n" ); document.write( " $\"+T+=+x+%2B+.5%2A%28+130+-+x+%29+\"$ ( in dollars )\r
