Ok, you'll need to find the volume of the concrete required for this job.
\n" ); document.write( "Recall:
\n" ); document.write( " $\"V+=+L%2AW%2AD\"$ where L = length, W = width, and D = depth, so...
\n" ); document.write( " $\"V+=+%2814%29%285%29%280.75%29\"$
\n" ); document.write( " $\"V+=+52.5\"$ Cu.yds
\n" ); document.write( "If each cubic yard of concrete costs $4.75, the 52.5 cubic yards will cost 52.5 times $4.75
\n" ); document.write( " $\"C+=+%2852.5%29%284.75%29\"$
\n" ); document.write( " $\"C+=+249.375\"$ Since we are dealing with dollars, we round up the nearest hundreth to get:
\n" ); document.write( "C = $249.38 \n" ); document.write( "

\n" );
