The body mass index is a measure of the risk of heart disease. It is given by the following formula:\r
\n" ); document.write( "\n" ); document.write( " I = 704.5 W\r
\n" ); document.write( "\n" ); document.write( "H2 Where W = weight in lbs and H = height in inches \r
\n" ); document.write( "\n" ); document.write( " An index greater than 25% indicates that a person IS at risk for a heart attack. If Mary’s height is 65 inches what should her weight be maintained at or under?
\n" ); document.write( ":
\n" ); document.write( "I am going to assume that the formula should be:
\n" ); document.write( "I = \"704.5W%2FH%5E2\";
\n" ); document.write( ":
\n" ); document.write( "Find W
\n" ); document.write( "\"704.5W%2F65%5E2\" =< 25
\n" ); document.write( "\"704.5W%2F4225\" =< 25
\n" ); document.write( ":
\n" ); document.write( "Multiply both sides by 4225 and you have:
\n" ); document.write( "704.5W =< 25*4225
\n" ); document.write( ":
\n" ); document.write( "704.5W =< 105625
\n" ); document.write( ":
\n" ); document.write( "Divide both sides by 704.5 and you have:
\n" ); document.write( "W =< \"105625%2F704.5\"
\n" ); document.write( "W =< 149.9 lb:
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution on good calc: enter: (704.5*149.9)/65^2 = 24.995 ~ 25%\r
\n" ); document.write( "\n" ); document.write( "
