A part-time gym membership costs one-quarter of the cost of a full-time gym membership. We have 20 part-time members and 30 full-time members. We know that the monthly amount that the gym collects from its members is $7000. What is the cost of a full-time membership?
\n" ); document.write( "-----------
\n" ); document.write( "Equations:
\n" ); document.write( "Value:: p = (1/4)f
\n" ); document.write( "Value:: 20p + 30f = 7000
\n" ); document.write( "-------
\n" ); document.write( "Substitute for \"P\" and solve for \"f\":
\n" ); document.write( "20(1/4)f + 30f = 7000
\n" ); document.write( "5f + 30f = 7000
\n" ); document.write( "35f = 7000
\n" ); document.write( "f = $200 (cost of a full-time membership)
