document.write( "Question 91411: 5) For the following function, C computes the cost in millions of dollars of implementing a city recycling project when x percent of the citizens participate. C(x)=1.5x/100-x
\n" ); document.write( "
\n" ); document.write( "a) Using this model, approximately what is the cost if 40% of the citizens participate?\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "b) Using this model, estimate the percentage of participation that can be excepted if $5 million is spent on this recycling project? Set up an equation and solve algebraically. Round to the nearest whole percent.

C(X)=1.5X/(100-X)
\n" ); document.write( "C(40)=1.5*40/(100-40)
\n" ); document.write( "C(40)=60/60
\n" ); document.write( "C(40)=1 MILLION IS THE COST.
\n" ); document.write( "5=1.5X/(100-X)
\n" ); document.write( "5*(100-X)=1.5X
\n" ); document.write( "500-5X=1.5X
\n" ); document.write( "500=1.5X+5X
\n" ); document.write( "6.5X=500
\n" ); document.write( "X=500/6.5
\n" ); document.write( "X=77 % NEEDED TOP PARTICIPATE FOR THE $5 MILLION COST.
\n" ); document.write( "
\n" );
