document.write( "Question 909238: All the units in an apartment building have either one or two bedrooms. The five story building has 10 apartments on each floor. Each one bedroom unit rents for $425 per month and each two bedroom unit rents for $550 per month. When all of the units are rented, the total monthly income is $25,000. How many one bedroom units does the apartment building have ?\r
\n" ); document.write( "\n" ); document.write( "I have put it into two equations:
\n" ); document.write( "x+y=50
\n" ); document.write( "425x+550y=25000\r
\n" ); document.write( "\n" ); document.write( "Then I put it in matrix equation format:
\n" ); document.write( "[ 1 2 ] [x]= [ 50 ]
\n" ); document.write( "[425 550] [y]= [25,000]
\n" ); document.write( "*I couldn't make the brackets go around the 2 rows but just know that
\n" ); document.write( "[1 2 ]
\n" ); document.write( "[425 550] is one bracket around the whole thing if that makes sense*\r
\n" ); document.write( "\n" ); document.write( "I'm supposed to put it in the calculator but I don't know how to put it in.
