THE BILL FOR FIVE GLASSES OF APPLE JUICE AND FOUR SALADS IS $9.50,BUT THE BILL FOR FOUR GLASSES OF APPLE JUICE AND FIVE SALADS IS $10.30.WHAT WOULD BE THE BILL FOR A GLASS OF APPLE JUICE AND A SALAD?
\n" ); document.write( "------------------------------
\n" ); document.write( "Equations:
\n" ); document.write( "5a + 4s = 9.50
\n" ); document.write( "4a + 5s = 10.30
\n" ); document.write( "----------------------
\n" ); document.write( "Multiply thru 1st by 4.
\n" ); document.write( "Multiply thru 2nd by 5.
\n" ); document.write( "-----
\n" ); document.write( "20a + 16s = 4*9.50
\n" ); document.write( "20a + 25s = 5*10.30
\n" ); document.write( "--------
\n" ); document.write( "Subtract 2nd from 1st and solve for \"s\":
\n" ); document.write( "9s = 13.50
\n" ); document.write( "s = $1.50 (price of one salad)
\n" ); document.write( "-----
\n" ); document.write( "Substitute into 5a+4s = 9.50 to solve for \"a\":
\n" ); document.write( "5a + 4*1.5 = 9.50
\n" ); document.write( "5a + 6 = 9.5
\n" ); document.write( "5a = 3.5
\n" ); document.write( "a = 0.70 (price of one apple juice)
