Let x = number of hammers sold
\n" ); document.write( "Let y = number of wrenches sold
\n" ); document.write( "the $ received for hammer sales are : $3x
\n" ); document.write( "the $received for wrench sales are : $2.50y\r
\n" ); document.write( "\n" ); document.write( "**If he sold 4 times as many hammers as wrenches, then
\n" ); document.write( "x=4y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We know the total sales are $609, so we can write the equation as
\n" ); document.write( "Total $ = Hammer $ + Wrech $:
\n" ); document.write( "609=3x+2.50y
\n" ); document.write( "by using x = 4y we can rewrite this equation as:
\n" ); document.write( "609=3(4y)+2.5y\r
\n" ); document.write( "\n" ); document.write( "Clear the parentheses and combine like terms:
\n" ); document.write( "609=12y+2.5y
\n" ); document.write( "609=14.5y\r
\n" ); document.write( "\n" ); document.write( "Divide both sides by 14.5 to isolate the variable:
\n" ); document.write( "42=y\r
\n" ); document.write( "\n" ); document.write( "So he sold 42 wrenches
\n" ); document.write( "and 4*42 = 168 hammers\r
\n" ); document.write( "\n" ); document.write( "this makes sense because 42*$2.5 = $105
\n" ); document.write( "and 168*$3=$504
\n" ); document.write( "and %504+$105=$609
\n" ); document.write( " \n" ); document.write( "
\n" );
