In a laboratory, there were just enough microscopes, test tubes, and calculators so that every 3 students had to share a microscope, every 4 students had to share a test tube, and every 5 students had to share a calculator. If the sum of the number of microscopes, test tubes, and calculators used by the class was 94, how many students were in the class?
\n" ); document.write( "-----
\n" ); document.write( "# of microscopes = x/3
\n" ); document.write( "# of test tubes = x/4
\n" ); document.write( "# of calculators = x/5
\n" ); document.write( "Solve:
\n" ); document.write( "x/3 + x/4 + x/5 = 94
\n" ); document.write( "--
\n" ); document.write( "Multiply thru by 60 to get:
\n" ); document.write( "20x + 15x + 12x = 60*94
\n" ); document.write( "---
