A small firm produces both AM and AM/FM car radios.
\n" ); document.write( "The AM radios take 15 h to produce, and the AM/FM radios take 20 h.
\n" ); document.write( "The number of production hours is limited to 300 h per week.
\n" ); document.write( "The plant’s capacity is limited to a total of 18 radios per week, and existing orders require that at least 4 AM radios and at least 3 AM/FM radios be produced per week.
\n" ); document.write( "Write a system of inequalities representing this situation.
\n" ); document.write( "Then, draw a graph of the feasible region given these conditions, in which x is the number of AM radios and y the number of AM/FM radios.
\n" ); document.write( "----------------------------
\n" ); document.write( "Domain and Range:
\n" ); document.write( "4<=x<=18
\n" ); document.write( "3<=y<=18
\n" ); document.write( "------------------
\n" ); document.write( "Quantity Inequality:
\n" ); document.write( "x+y<=18
\n" ); document.write( "--------------------
\n" ); document.write( "Production Inequality:
\n" ); document.write( "15x + 20y <= 300
\n" ); document.write( "-----------------------
\n" ); document.write( "Solve Quantity and Production for \"y\" :
\n" ); document.write( "y <= -x+18
\n" ); document.write( "y <= (-3/4)x + 15
\n" ); document.write( "-------------------------
\n" ); document.write( "Graph:
\n" ); document.write( "Draw vertical lines at x = 4 and at x = 18
\n" ); document.write( "Draw horizontal lines at y = 3 and at y = 18
\n" ); document.write( "Note: These limit the domain and the range of the solution set
\n" ); document.write( "-------------------------
\n" ); document.write( "Graph the boudary lines of the Quantity and production Inequalities:
\n" ); document.write( "\"graph%28400%2C300%2C-10%2C30%2C-10%2C30%2C-x%2B18%2C%28-3%2F4%29x%2B15%29\"
\n" ); document.write( "Darken the area in the feasible solution area that is below both
