Renting an Apartment: Three students are planning to rent an apartment for a year and share equally in the cost. By adding a fourth person, each person could save $75 a month. How much is the monthly rent?
\n" ); document.write( ".
\n" ); document.write( "Let x=rent per student if 3 room mates
\n" ); document.write( "then
\n" ); document.write( "12(3x) = \"total rent for 3 room mates (in a year)\"
\n" ); document.write( ".
\n" ); document.write( "If four students rent
\n" ); document.write( "12(4(x-75)) = \"total rent for 4 room mates\"
\n" ); document.write( ".
\n" ); document.write( "set them equal and solve for x:
\n" ); document.write( "12(3x) = 12(4(x-75))
\n" ); document.write( "3x = 4(x-75)
\n" ); document.write( "3x = 4x-300
\n" ); document.write( "300+3x = 4x
\n" ); document.write( "$300 per month = x
\n" ); document.write( ".
\n" ); document.write( "So, that's $300 per month for each room mate (if there are only 3 of them)
\n" ); document.write( ".
\n" ); document.write( "Monthly rent = 3(300) = $900 per month\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
