\n" ); document.write( "x = number of ten dollar bills
\n" ); document.write( "48-x = number of twenty dollar bills\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "10x = value of all the ten dollar bills
\n" ); document.write( "20(48-x) = value of all the twenty dollar bills\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "10x+20(48-x) = total value
\n" ); document.write( "10x+20(48-x) = 880
\n" ); document.write( "10x+960-20x = 880
\n" ); document.write( "-10x+960 = 880
\n" ); document.write( "-10x = 880-960
\n" ); document.write( "-10x = -80
\n" ); document.write( "x = -80/(-10)
\n" ); document.write( "x = 8
\n" ); document.write( "48-x = 48-8 = 40\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer:
\n" ); document.write( "8 ten dollar bills
\n" ); document.write( "40 twenty dollar bills\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( "8+40 = 48 bills total
\n" ); document.write( "8*10+40*20 = 880 dollars in total value
\n" ); document.write( "Both conditions are met to verify the answers above.
\n" ); document.write( " \n" ); document.write( "
