\n" ); document.write( "Method 1
\n" ); document.write( "(3 drinks)/(9 dollars) = (5 drinks)/(x dollars)
\n" ); document.write( "3/9 = 5/x
\n" ); document.write( "3x = 9*5 ... cross multiply
\n" ); document.write( "3x = 45
\n" ); document.write( "x = 45/3
\n" ); document.write( "x = 15 dollars\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Method 2
\n" ); document.write( "3 drinks cost $9, which means the unit price is 9/3 = 3 dollars per drink.
\n" ); document.write( "Five such drinks gets a total price of 5*3 = 15 dollars\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Method 3
\n" ); document.write( "3 drinks = $9
\n" ); document.write( "3/3 drinks = $9/3
\n" ); document.write( "1 drink = $3
\n" ); document.write( "5*1 drink = 5*$3
\n" ); document.write( "5 drinks = 15 dollars
\n" ); document.write( " \n" ); document.write( "
