A school wants to purchase some round tables and some rectangular tables.
\n" ); document.write( " The costs of one of one round table and one rectangular table are $20 and $25, respectively.
\n" ); document.write( " The school wants to spend at most $1000.
\n" ); document.write( " Represent this problem for the purchase of x round tables and y rectangular tables graphically.
\n" ); document.write( ":
\n" ); document.write( "let x = no. of round tables
\n" ); document.write( "let y = no. of rect tables
\n" ); document.write( "then
\n" ); document.write( "20x + 25y =< 1000
\n" ); document.write( "put the equation in the slope intercept form
\n" ); document.write( "25y =< -20x + 1000
\n" ); document.write( "divide by 25
\n" ); document.write( "y =< -.8x + 40
\n" ); document.write( "plot this equation, let's use x=10, x=30
\n" ); document.write( " x | y
\n" ); document.write( "------
\n" ); document.write( "10 | 32
\n" ); document.write( "30 | 16

\n" ); document.write( "Area of feasibility at or below the line
\n" ); document.write( "For example, if you get 25 round tables, you can get 20 rect tables, (green line)
\n" ); document.write( "25 * $20 = 500
\n" ); document.write( "20 * $25 = 500
\n" ); document.write( "---------------
\n" ); document.write( "total is $1000
