I just need help in how to graph this problem What would be the break-even point if a firm set a unit selling price of $100 when total fixed costs were $100,000 and varable costs per unit were $80.
\n" ); document.write( "-----------------------------
\n" ); document.write( "Revenue = 100x
\n" ); document.write( "Cost = 80x + 100,000
\n" ); document.write( "-------------------------
\n" ); document.write( "Graph y = 100x
\n" ); document.write( "If x = 0, R = 0 giving you point (0,0)
\n" ); document.write( "If x = 5, r = 500 giving you point (5,500)
\n" ); document.write( "---
\n" ); document.write( "Plot those two points and draw a line thru them.
\n" ); document.write( "That is the Revenue graph
\n" ); document.write( "----
\n" ); document.write( "Graph y = 80x + 100,000
\n" ); document.write( "If x = 0, y = 100,000 giving you point (0,100000)
\n" ); document.write( "If x = 5, y = 80*5+100000 = 100400 giving you pont (5,100400)
\n" ); document.write( "Plot the two points and draw a line thru them
\n" ); document.write( "That is the Cost graph.
\n" ); document.write( "------------------------------------
\n" ); document.write( "\"graph%28400%2C300%2C-50%2C7000%2C-50%2C600000%2C100x%2C80x%2B100000%29\"
\n" ); document.write( "----
\n" ); document.write( "The intersection is where 100x = 80x+100,000
\n" ); document.write( "20x = 100000
\n" ); document.write( "x = 5000
\n" ); document.write( "There y = 100*5000 = 500,000
\n" ); document.write( "-------------------
