A marketing manager for a publishing company has a 6 foot by 8 foot banner to be used when setting up booths at educational conferences.
\n" ); document.write( " She decides add more zing to the booth by increasing the square footage by 50%, and plans to accomplish this by increasing each of the dimensions by the same amount.
\n" ); document.write( " What will the new dimensions be?
\n" ); document.write( ":
\n" ); document.write( "Find the area of the new banner
\n" ); document.write( "1.5(6*8) = 72 sq/ft
\n" ); document.write( "Let x = the amt of increase required to accomplish this
\n" ); document.write( "(x+6)(x+8) = 72
\n" ); document.write( "FOIL
\n" ); document.write( "x^2 + 8x + 6x + 48 = 72
\n" ); document.write( "x^2 + 14x + 48 - 72 = 0
\n" ); document.write( "x^2 + 14x - 24 = 0
\n" ); document.write( "Use the quadratic formula: a=1; b=14; c=-24
\n" ); document.write( "I got a positive solution: 1.544 ft
\n" ); document.write( ":
\n" ); document.write( "What will the new dimensions be?
\n" ); document.write( "6+1.544 = 7.544 ft is the new width
\n" ); document.write( "8+1.544 = 9.544 ft is the new length
\n" ); document.write( ":
\n" ); document.write( "Check: 7.544 * 9.544 ~ 72 sq/ft \n" ); document.write( "
\n" );
